This is after about a year and two months of closure due to a serious malfunction that occurred about nine days after its opening * initially it will work at half of its maximum power, but no particle accelerator has reached that even so far
The Large Hadron Collider (LHC) experiment is scheduled to be powered up for the first time on Saturday morning at the earliest. This was announced by Saran management in Geneva, the international body that operates the accelerator.
The engineers intend to launch a beam of subatomic particles along the entire 27 kilometers of the circular accelerator tunnel.
As we recall, the accelerator was first activated on September 10, 2008, but nine days later, a fault occurred in one of the seams between two superconducting magnets, which caused a ton of liquid helium, which is used to cool the facility to 1.9 degrees Kelvin, to leak into the tunnel. The facility has since been closed to allow for repairs. It turned out that it was necessary to replace magnets and repair about 200 electrical connections. The engineers also installed an early warning system that may prevent this type of malfunction that could cause the entire facility to be paralyzed. It is estimated that the cost of the repairs was about 30 million dollars.
The machine that cost about 10 billion dollars, located under the border between France and Switzerland, is designed to shed light on fundamental questions about the universe. The facility has been shut down for repairs since the malfunction that occurred in September 2008.
The accelerator will mimic the conditions that occurred in the first moments after the Big Bang. It will do this with the help of about 1,200 superconducting magnets that fill the tunnel. The magnets will direct the proton beams in opposite directions around the ring at a speed close to the speed of light. In several places around the tunnel the proton beams collide with each other. Physicists hope to stretch the laws of physics and observe new subatomic particles in the fragments of these collisions.
On Wednesday, the facility was transferred from the team responsible for the hardware and equipment to the operations team. During the transfer ceremony, a beam was transferred (in one direction only) in the LHC ring. On Saturday, a more continuous run will begin to test the devices and experimental facilities scattered along the tunnel, and within a few weeks it will be possible to perform the first collision.
The LHC was designed to operate at energies of 7 trillion electron volts, but in the first months it will be operated at half the power, but this is also a power that has not yet been tried in any particle accelerator, and there are scientists who hope to reach results already in these dynasties.

Good luck to the particle accelerator, for better or for worse, what amazed me the most was that there was a TV show about it and there they said that the construction started 30 years ago! (in secret).
So I ask myself, I wonder how many other things there are that have long been started to build and we will soon find out..
Mr. "to the point".
You probably don't visit here much because there are a lot of jokes here.
If you visited here a lot, you would have also noticed that the reaction of a point - it was also a joke.
Besides, you probably meant HAL and not HEL
Look I love science, especially fiction D:, I visit this site with all the professors and university students who speak high language, but really almost no one here understands jokes and it's a shame even HEL 9000 could tell a good joke and laugh (:
Besides, every science fiction turns out to be 99.99% true in the end, if there were no crazy ideas there would be no genius ideas.
zen koan,
The intention is that everyone returns to the one and only and special scientist site.
"All things return to the One.
What does one return to?"
I heard there is such a thing as a "gravitational singularity" the one repeats?
It's really interesting, for example when Chernobyl exploded, all of Europe glowed, what would happen if something similar happened there? Will the whole star shine? …
But let's hope nothing happens, in the end we always learn from history (the dinosaurs said)...
Thanks, if you were to read all kinds of things written by internet surfers, you would see that people write scary things, but thanks anyway
Carrie, if you followed the science site seriously you wouldn't need to look for reassurance. We have already explained here that the processes in the accelerator are not more energetic than normal cosmological processes that happen around us every moment, therefore there is no fear for any scientist from any experiment he will do in the accelerator.
to the point
I meant seriously, it's funny to me that it really scared me then... if it's possible to get a more serious answer please
Carrie, you have nothing to worry about, you won't feel anything 🙂
To my father or someone else who understands accelerators
Wow, I read comments on websites and I read that people are trying to scare that the accelerator will lead to the destruction and destruction of the world and it takes me back a year, that's why I was afraid that something would happen because I'm afraid of dying young and I don't understand what the purpose of the experiment actually is and I'm very confused. I'd love to get an answer like when it's supposed to Let the first collisions occur and whether to believe what is written
Have a good and wonderful week
In Basel we founded the Jewish state, and in Geneva we destroyed the earth.
From Geneva the evil will open.
This experiment has been bothering me since September of last year. If I could cancel the experiment, I would do it even though I talked to several physicists and now I understand that there is no threat from the accelerator. Anyway, I hope that when they activate me then I can finally relax.
Cheers, peace
You didn't read my comment correctly. I said that the book claims that the theory that claims mass is dark
does not exist but arises from Newton's inaccurate equations, a theory called "MOND theory",
It is the one that was allegedly disproved by "Sloan's sky survey", and not the dark mass theory accepted by
Most of the scientific community. Of course, the author fully supports the dark matter theory, and cites the refutation of the competing theory as a reinforcement of his words. Hope everything is clear now.
Peace be upon Yehuda
It's a shame that we can't have a fruitful discussion on this matter, but I will respect the site's wishes.
Hope your private path will shed light on the subject.
to straw man and others
I was previously asked by Avi Blizovsky, the owner of the site, not to expand again on my unacceptable explanations of the dark mass here on the site and I respect his wish.
A response to your words will be found on my website "Science and Nature" which you can reach by clicking on my name in the title of this response

For Itzik, if you haven't heard, a huge demonstration of ultra-Orthodox is being organized in the mountains of Switzerland wearing shorts and blowing yodel mountain trumpets. They are also going to throw away cow diapers full of cow poop.
Hello straw man. I also read the above book and it is not true. He does not claim that the dark matter theory has been disproved. I don't know where to get it from.
Yehuda Shalom
I read with great interest about the theory of the dark mass which does not actually exist
and stems from Newton's equations that need correction, but in the book "Parallel Universes" by Michio Kaku
He claims this theory was disproved in 2004 by "Sloan's sky survey". Do you know anything about it?
to Itzik
Not to mention that they are going to run the protons precisely on our holy Shabbat.
But, another vision for the time being and there may be nothing but small squeaking sounds. Nevertheless, it will be difficult to move some protons who for over a year thought that they had come to rest and rest.
Also, let's not forget that most likely during this period various insects and Swiss mice settled in the facility, not to mention bird nests.
I believe that in the end the facility will play a role for evolutionary research in a unique atmosphere of electromagnetic radiation and this is no small thing.
Suggests that the new productions receive the suffix Seranos, for example from Cocus Seranos
What's funniest is that they claim that the cost of the repairs is about thirty million dollars, which is completely nonsense, because just waiting a year plus to operate a body in which ten billion dollars were invested, which has the potential to live for ten years minus plus plus interest and plus the salary of thousands of employees, is worth about a billion dollars, if not more, in my estimation !
So Shabbat Shalom and it's not fair that I belittle the people who are trying so hard - most likely the envy is speaking from my throat and also maybe the fear that in everything there will be proof of the existence of the dark mass that I hate.
And we will get to see the coming of the Messiah and the discovery of the hygge boson, wings or whatever.
I believe Christ will come first

Not to mention they are going to run it on Saturday.
Do the ultra-Orthodox in Switzerland know about this?
Are you not organizing some Shabbat demonstration in the thousands?
I suggest that accelerator operators start small.
First of all, they will take a rooster to atone against all kinds of birds that might drop croissants on the accelerator.
Then they will put a horseshoe at the entrance and maybe also a mezuzah
Then I suggest running the Protons around the accelerator on a bike or Corcont and don't forget to rest along the way just to be safe.
Only at the last stage should it really be run and preferably only in 2012 so that there is someone to blame - Nostradamus, Maya or just the Jews.
Other than that, I really have my fingers crossed for them
with a smile

I think there are superconductors at higher temps than very close to absolute zero. I don't remember exactly what the element is that becomes a superconductor at higher temps, but I'm almost certain there is one around 200 degrees Kelvin. Apparently there is also a meaning to who is the conductor.
Imagine they invent a superconductor at room temperature.
It will be possible to get rid of tens and hundreds of tons of equipment in this facility. Not to mention the investment of energy in cooling the helium and the helium itself, which would allow it to be released freely in nature.
So where does the matter of room temperature superconductors stand today?
Nice, I'm so excited to know what the findings of this research will be when the accelerator is activated and as much as possible will lead to a new world of space science research!!!!
