PSI - Paul Scherrer Institut

SENIS Hall Probes are used for monitoring of beam control magnets in the PSI's proton therapy system. The initial patient therapy started in February 2007. According to PSI, the radioactive area (gamma and neutron radiation) did not harm the SENIS Hall Probes. “We apply SENIS Hall probes for monitoring of dipole magnets in our PROSCAN accelerator. Protons are generated with a maximal energy of 250MeV and a maximal beam current of 500uA, so that gamma and neutron rays arise. The gamma rays have an energy spectrum of several MeV. SENIS Hall probes are successfully exposed to the radiation since several years an we haven’t seen any performance deterioration”,  says Dr. Marco Negrazus of PSI, in May 2016.  http://p-therapie.web.psi.ch/proscan.html
