Thousands of scientists are waiting impatiently, including representatives of the Technion, Tel Aviv University, and the Weizmann Institute. From today begins a massive line of Israelis in the control room of Atlas * The beam that will be launched today will be one-way and the serious collisions are expected in early 2009
For the updated news: The first beam was fired at the particle accelerator in Sarn (regular updates)
The moment when ten Israeli scientists, and about 20 doctoral students from three higher education institutions, like thousands of their colleagues from all over the world, has arrived. Today, Wednesday, September 10, at 09:30 Israel time, the largest scientific instrument in the world - the Large Hadron Collider (LHC for short) - will start operating at the CERN particle physics laboratory in Geneva.
The scientists and engineers at the LHC injected the first protons into the accelerator over two weekends in August. During these experiments, the beams moved only in parts of the circular accelerator tunnel, the total length of which reaches 27 kilometers. Israel is represented by ten scientists from three academic institutions: Tel Aviv University, the Weizmann Institute and the Technion. They all work on the same system - the muon detector in the Atlas experiment, one of the largest of the four experiments scattered over the CERN tunnel. They are joined by another twenty doctoral students from the three institutions, studying the relevant fields.
We spoke with representatives from each of the three Israeli institutions about their feelings. Prof. Shlomit Terem, the Technion, tells the Hidan site, phones from her office
At CERN: "that we lived and existed and arrived at this time. We have worked for many, many years and we are finally getting the sheaves. Time is short and the work is plentiful."

- Is the Earth about to be swallowed by a black hole? (Yel Petar, 30/5/2008)
Prof. Giora Mickenberg from the Weizmann Institute, also in Geneva: "We started working on this experiment in the first planning stages from 1992. This is a large part of the academic life of all of us and suddenly in the last six months when you see the impacts of cosmic radiation on the detectors and you see that the detectors are working and doing what they need to do, now we finally see a real beam. its a dream. When we got together, we were a small group of Israeli and Japanese scientists and we thought about what we could do to take a significant part in the experiment and when we drew the giant wheels containing the muon detector on paper it looked like something that would never come true and now when we see it, we wonder: did we do that?
Prof. Yaron Oz, Head of the School of Physics and Astronomy at Tel Aviv University: "Tomorrow (Wednesday, the interviews took place on Tuesday) will be a festive day, we are going to launch one beam and not have a collision. The great achievement will be when they manage to track it and direct it properly because it has to be very precise. In the second phase, around October, a second beam will be integrated and the main experiments will be carried out during the first year. In the first stage it will not be at the planned energy but at a lower energy."
Prof. Terem: "Until now we have collected data on the impact of cosmic rays on the detectors. No one has experience how the detectors will behave in the environment of colliding proton beams at the LHC, how many particles they will collect, which particles. We have prepared a number of work methods so that we can adapt to the situation on the spot."
Is there any ceremony expected?
Prof. Terem: "CERN's public relations department organizes a place where journalists from all over the world can observe what is happening in the control room of the accelerator, and the control rooms of the experiments and give them explanations. I don't know about cutting films, I'll probably be at work."
Prof. Mickenberg is preparing for several sleepless nights, to make sure that all the systems are working properly: "We must not forget that the accelerator is one of the most complicated things that humanity has built, even more than the space programs. With all due respect to the Apollo program. It's just a box that you send out with some detectors and control systems. Here we are talking about a hundred million different detectors in one experiment. I always like to make the comparison - 40 million times per second the particles are supposed to collide, and the information is captured through 100 million different detectors, each of which has a few bits of information. If you multiply these three numbers, it is by a factor of one hundred more than the amount of information that goes through all the phone calls in the entire world and you manage to filter it, and transfer it in very short times."
What is expected from the scientific point of view?
Prof. Terem: "They won't discover the Higgs on the first day. In terms of physics, nothing new is expected tomorrow. Only one beam will be launched, in order to give us the possibility to verify the operation of the instruments in the presence of beams. Then in as short a time as possible they will reach a state of colliding beams. In the first stage, one beam will be launched at a time, and even if two beams are launched, they will not bring them into collision. We need to calibrate the acceleration and collision system and close all the edges. These are systems that could not be tried as long as we were working on the construction of the detectors and at best sections were tested. We expect to see one beam make a full rotation. There will be a segment where they will cause particles to be sprayed into Atlas so that we can see how Atlas reacts to a large shower of particles entering it and how we detect it. They will slowly move to two separate beams in each direction. Each process will be examined separately and eventually we will reach conflicts."
And what is your role, the scientists who are at CERN on the first day?
We will be in the control room and staff it with the greatest experts to find out if there will be discrepancies with the forecast and decide in real time on the methods of action. Among other things, we will check the detectors themselves, for example if too much current will pass through them. The experts will be there to keep everyone on their system and see how it works.
What do you expect to find out?
Prof. Oz: "In the accelerator, two proton beams will run that collide with each other, with an energy that is 10 times the energies at which experiments have been carried out to date. One of the basic goals is to find the Higgs boson - the particle that, according to the theory, is responsible for the mass formation mechanism. But there are many other theories that are being tested - super symmetry which predicts that every particle we know today has a brother that we have not discovered until today, for example the electron has a brother called a selectron which has exactly the same properties except for one thing - the spin.
Another thing that is going to be checked is whether there are additional dimensions to the universe beyond the three space and one time that exists. If there are any in the energy of the accelerator, then there is also the possibility of the formation of tiny black holes that was the trigger for people's fear. Oz says that the huge project of the accelerator should be appreciated, especially in light of the fact that it was not built on the basis of existing technology, but new technologies had to be developed. "The most interesting thing is that the accelerator will reach energies where there will be surprises. No one can tell you for sure what will turn out to be the most interesting thing for us. They had a difficult time where they had to build and I hope there will be results. Theorists will also have experimentally generated data. A very interesting period in basic physics is expected in the coming decade."
An Israeli national project
"This is a national project as far as Israel is concerned," says Prof. Oz. "The three groups are equally involved in the construction, testing of the detector and its installation and then in the data analysis phase. The funding is state funding, mainly the Planning and Budgeting Committee of the Council for Higher Education, the Ministry of Science and Technology and the Office of the Chief Scientist. Israel has signed an agreement with Saran on cooperation at the national level."
What can be said about Israeli cooperation?
"We are all working on the same specific project of the ion detector. So far we have been busy building, testing and placing the axle and then the analysis phase and the shift phase - when the experiment is carried out there will be shifts to monitor the experiment, locate possible faults, and of course collect the data. The control room will be constantly staffed not only by faculty members but also by students who are doing a doctorate in the field. Already at this moment there are about ten faculty members from the three institutions at CERN. And the number of students is about double that.
Prof. Mickenberg: "The Israeli community is very active and the beautiful thing is that we are an example to most communities, some of them have learned from us and imitated us. We work together and then the impact is greater. We convinced the Japanese and they also do as we do and conduct excellent cooperation between themselves and with us."
Apart from that, there is a strong presence here of the Israeli industry, which participated massively as part of the Israeli contribution to CERN, even though we are only in observer status. The international cooperation - including with those who consider themselves our enemies - was also successful. When there is a real engineering and scientific project, it is very easy for people who come from different cultures or religions to work together. Our engineers and technicians worked for three years together with engineers and technicians from Pakistan. The huge wheels on which the Israeli detectors are located were mounted on jigs - precise metal structures on which the aluminum structures built in Israel were glued, on which the detectors, cables and all service systems were assembled. This was the pride of the director of the nuclear agency of Pakistan. We also worked with Palestinian and Lebanese physicists. When there is a defined project at the edge of technological capability, all political concepts play no role. We are human and proud of what we do."
Prof. Oz adds that the European Union itself was built on the Saran model, in which several countries band together and perform a joint experiment without the need of a specific country. The accelerator was the driving force for no small technological achievements. It is a fact that the model was successful, while the construction of a similar accelerator in the USA failed. It is probably easier to do such projects through a mechanism of international cooperation.
Is it possible to reassure the public that the end of the world will not come tomorrow?
Prof. Terem: "Many scientists conducted a million tests and calculations that nothing would happen." There are some people who are not in the field like that German chemist who decided he knew better than all the experts. These people wanted to get publicity thanks to the panic. The journalists are also responsible for this like the one who wrote the news in Walla which was indeed true and wrote that everyone except that German chemist who is not an expert in the field says there is no problem, but his editor gave the title 'The end of the world on Wednesday.'
"As Ehud Duchovni wrote in YNET, this is Babylon. It's just a shame they don't listen to him. After Wednesday will come Thursday, and in a few weeks we may begin to learn more about the universe and nature. And besides that, life will go on as usual." Prof. Mickenberg also addressed the issue briefly: "The European Court rejected the petition, and stated that there is no danger."

And they are really crazy!!!! To do an experiment to know how the world was created and maybe even with this help to destroy it!!!!!! They don't care to take the risk that maybe they and all of us and the whole world will die!!!!!!!
Why do they even allow them to do this retarded experiment????
They invested so much money to possibly destroy the world?? What is happening to you people???? Until the world is destroyed there is still time so why reduce the remaining time??????
Besides, if you don't know, they postponed this experiment until the spring because they had all kinds of problems....
It's really scary!!!!!! I'm afraid of all these things that are said about the end of the world and all the visions that are constantly talked about!!!! :(
All the time there are new things there are those who say in 2012 and others say from this experiment and others say....
I don't know who to believe anymore?!!!
But admit that it's really scary all these things!!!!!!!
And another thing, you are very cowardly, whatever happens will happen
Once again, nothing will happen, what do you want to die by force, take a knife and kill yourself!!
Itzik:
I don't understand your plan.
What is that magnetic bottle and why will the black hole strive to stay in its center?
Michael
If the black hole is left with the electric charge that can be continued or repelled by a magnetic field (depending on its charge when it is created). So in theory it is possible to imprison him in say a magnetic bottle if he is beyond the event horizon of that black hole?
For anyone who thinks it's a waste of time or money or whatbar:
You are welcome to do what you want with your time and money and stop telling scientists what to do.
I have not yet seen that steams solved any problem.
Itzik:
Beyond the student's words - which are true - a black hole has no magnetism.
The only properties that can be measured about it are mass, electric charge and angular momentum.
I have a question. At what point will the scientists be able to take simple hydrogen, which is the cornerstone of the universe, and create from it, artificially, other materials such as gold, silver and diamonds, by fusing hydrogen atoms together?
my father
Your last reference sounds like "disappointed Polish mother", don't worry everyone will be smart
Good and intelligent. You need patience!
Yours, from "Polishness or not to be".

to Reali,
Indeed I justify you in one thing regarding the distribution of the money. They should have given a "small" portion (it's still 4 billion or so) for the benefit of improving education, and if not for that, then at least for the benefit of an algorithm that corrects spelling errors for people and even gives them an electric shock ;)... and it really doesn't matter to me if the commenter is a child or an adult, For me, I would filter comments with over 4% spelling errors. (See this as a recommendation).
In any case, in my humble opinion, the systemic evidence is for the long-term future and not the short-term, there is something true in what you say, but just so you know, there are a lot of scientists working in the fields you mentioned, because after all, in the end, everything is money and scientists who develop a device for water desalination will be rich... that's why I guess That money and the "contribution to humanity" whiten the embers.
Demosthenes.
All the obstinate-religious reactions show one thing. Who is in charge of education in our country? And what will come out of it instead of engineers and doctors. Apparently Israel's economic future lies in spell whisperers and X-rays.
I don't understand why they wasted more than 4 billion shekels, if today they just did the experiment, besides, why do we really have to die in a few more months? No, I say that the people of Israel are a virtuous people, and there is only one God, as long as we believe in Him, everything is fine.
What kind of brains do people have today ._.
Is there still a chance that the world will be swallowed by a black hole?
If so, how is it supposed to be, I mean, the black hole will swallow all of Earth at once, or it will slowly swallow all of Earth and it will still be possible to live until the black hole swallows the whole world, or the black hole will cause some reactions such as tsunamis and earthquakes Earth and then disappear?
I have to know this, because for two days now I've been waking up with stomach pains that come from stress because of the fear that the world will be swallowed by a black hole?!
to Itzik,
I think you are a bit confused. The protons have a positive electrical charge and are not magnetic.
These are two completely different features. One of the properties of an electric charge is that it is attracted or repelled (according to its sign) to a magnetic field, thus actually accelerating the protons.
I believe that if they discover a magnetic monopole it will be a very sensational discovery since according to the current theory in physics there are no magnetic monopoles. But there are electric monopoles.
I don't believe this nonsense and there is nothing to be afraid of!
And besides that it has no justified purpose!
Just think what a breakthrough for humanity we will have!!!
Please succeed, we are under pressure, children of the 1st grade, Bialik Rogozin campus
Early 2009 from what I understand.
Until then calibrate and calibrate again and again and again.
I am the house, I hope that you will succeed because we hate to die, we love you, thank you very much
I will understand today that it was a run of an accelerator to check if it works?
And when will there be a clash that is being talked about?
I think that in the end the very fact that in the State of Israel they treat it seriously and all the media updates what is happening ONLINE, I think that the news about the experiment and the project did not make it onto the agenda in most of the world.
This symbolizes the same thing for which the project was built.
Curiosity and desire to understand the world.
Well done to us. 🙂
It is very important to allocate resources to areas such as modern physics, without modern physics physics will not advance, if physics does not advance then it will be more difficult to achieve engineering achievements.
Regarding investment for existing problems, there is a lot of research and development in the field, clean energy, water, etc., the research and the money do not miss anything, there are scientists, engineers and money in every field.
In terms of research, only a handful of scientists deal with high energies.
another question
Is it possible to call the material in the fund "Monopoly"? The same theoretical magnet that you are looking for has one pole or does this refer to the material in a normal state? Or is it another magnetism? Monopole - a theoretical material with one magnetic pole. Mono - one pole - pole
Imagine a block of material with a magnetic property that only attracts or only pushes without two poles
A question for those who understand.
According to my understanding, protons of gold are accelerated because it is a heavy substance that strips it of its electrons so that they only have a positive charge so that the magnets can attract or push them in a circle during this entire phase the charge of the beam is positive.
Now my question is: if we suppose they collide with enough force to create a black hole, will the black hole still have positive magnetism? Or will this feature disappear?
Thanks for a qualified answer
4,7,8,9,10
It's not just that you're sitting in front of a computer screen, and while you're rambling and writing stupid comments, scientists from dozens of countries are doing what needs to be done to know a little more. After they know a little more, the science site will once again publish an article about new discoveries, and you'll again write retarded comments (but Of course, forget the current article).
That's how it is, the circle of life.
For number 5 - the answer is: yes.
To my father
Maybe, but you don't have to distribute the money directly to the poor. Perhaps also an additional 3 million dollars for more urgent applied research. Less sexy than modern physics but more urgent. I'm just saying that the order of priorities is distorted. Our company pays a fortune to a computer game developer and a pinch to a teacher. The company invests capital in theoretical research and neglects areas that may be very urgent in the near future. Lack of water for example. An international investment of such an amount ($8 billion) in a research project in the field of water desalination would have brought us as humanity to a better situation in less than a decade, I suppose.
My father, dear guy, science has not yet found solutions to the many problems that exist on Earth, and what is it doing instead? An experiment in a particle accelerator whose real result is unknown to any scientist who will not tell stories that there is no danger because no one knows it yet, everything the scientists know is done in theory only, and as is known theory sometimes does not reflect reality.
A particle or ion accelerator, it doesn't matter what we call the child, it's simply dangerous because we don't know how it will spread and with what intensity, it's unknown if it will cause damage to the tectonic plates and any change or not, so science will go looking for things for the benefit of humanity in the concept of the present and not the future instead of looking for a way to harm perfection this ball
I don't understand why they are excited that there are Israelis there because they allocated a percentage to each country anyway..
Good luck to our scientists though
for real Close the project, you got 3 more dollars for every poor person. Close the space project, another 2 (and all in annual terms). And what to do even in 40-50 years we will have to live and invent new inventions. Why turn off the tap and live today at the expense of the future? You are also personally saving for retirement.
A colossal waste of money. Why not invest such sums in research that has a direct and immediate impact on the quality of our lives such as clean energy, a solution to poverty and hunger, diseases and more...
is not that a loss ??? And I haven't mentioned the waste of money in the American space project...
Such discoveries take decades before they permeate applied science, and return the investment to the public. Applied research in the fields of medicine, agriculture and energy takes less time and is more urgent today. I agree that there are enough resources for everything but the order of priorities has gone wrong with the decision makers.
from where missiles. The serious kind. Dozens. hundreds as many as needed.
I'm sure they have a contingency plan that the powers in the world or at least
One of them knows about her and is ready to provide help if and when they need it.
They want to explore the dimensions of the world, they will see that the worlds from them do exist and can also be returned in time.
If everything I said is true and the scientists also see these possibilities, the whole matter will be kept a secret, and you will never hear from these experiments again.
Everything that is done underground is dangerous, and this has been proven many times.
And as they said here, the real danger is in a few months and then we'll see.
Sometimes science goes beyond science, to look for something that is already known and studied like the big bang is meant to be done in space not here.
And whoever says that the danger is in BLA either doesn't know what he's talking about, or doesn't want to know what the risks are in such a powerful particle accelerator.
More energy? from where???
Is this the same place described in Dan Brown's book Angels and Demons?
For "no" - even the results of the more serious phases of the experiment that will begin in a few months will certainly not lead to the end of the world, perhaps to small side effects such as a small number of weak earthquakes in the same area and perhaps some other things that are not really significant.
In the worst case, it will be possible to mobilize an even greater amount of energy than the one participating in the experiment and activate it in a counterintuitive manner, and then maybe a certain amount of people will be killed, but the world will remain standing.
What a shame for them if nothing came out of it haha they answered they invested 7.7 billion for this and over 10 years
They actually managed to calm me down.
Everyone calm down it will be fine!!!!!!
I don't think what they do tomorrow will bring the end of the world, only what they do in a few months
