Radiation test facilities in the new PS East Hall at CERN

At the CERN Proton Synchrotron (PS), the 24 GeV/c primary beam allows the operation of two new irradiation facilities. One is using directly the primary proton beam and the other one is using secondary particles (mainly /spl sim/1 MeV neutrons) produced in a cavity after a beam stopper. For both facilities, samples to be irradiated are brought to the irradiation positions by means of automatic shuttles. Designs, Monte Carlo simulations of particle spectra and background are presented as well as the performance achieved.
