Window of Opportunity

The experimental system: two nostrils from which exit ultrasonic beams of excited helium atoms (in blue) and of argon atoms or hydrogen molecules (in red). The blue beam passes through a magnetic device (in yellow) which causes it to bend, and merges with the red beam - then the argon atoms or hydrogen molecules undergo ionization, and enter the detector. The picture above shows a cross-section of the magnetic device.
