NA7
NA7 was an experiment at the Super Proton Synchrotron of CERN , which was conducted from 1977 to 1987. The aim was to measure the electromagnetic form factors of the pion and the kaon . Stephan Frank was the spokesman for the collaboration . Another prominent member of the collaboration was the later spokesman for the CMS experiment Guido Tonelli .
construction
Multi-wire proportional chambers (MWPC) made it possible to determine the momentum of the incoming particles, which came from a pion beam of the Super Proton Synchrotron with a purity of about 98% and an impulse of 300 GeV / c. As a sample was hydrogen used and served as a trigger scintillators before and after the sample. Five times eight MWPCs were used for the Vertex reconstruction. The spectrometer of the NA1 experiment completed the setup.
