NA5

NA5 was an experiment at the Super Proton Synchrotron of CERN , which was conducted from 1977 to 1980 and completed 1990th The aim was to research the inelastic scattering of hadrons using a streamer spark chamber and a one-armed spectrometer . The spokesperson for the collaboration was Peter Seyboth from the Max Planck Institute for Physics .

construction

Protons and anti protons at 200 GeV / c - pulse were at a rate of up to 10 ⁵ directed particles per second in various samples. Hydrogen , argon and xenon , for example , were used as samples . A streamer spark chamber, which was located in a magnetic field of 1.5 Tesla, was used to detect the products . The streamer spark chamber itself was filled with a helium - neon gas mixture which was under normal atmospheric pressure . The traces created in the chamber were recorded with three cameras. A spectrometer, consisting of seven magnetostrictive spark chambers, was connected to the streamer spark chamber . Three small multi-wire proportional chambers supported the spectrometer.
