Proton Irradiation Facility (OG 3207)

Our main activities concentrate on operation, maintenance and development of the particle tests facilities. They utilize PSI accelerator complex and offer different particle beams with user required parameters. Their main features are a user-friendly design and operation as well as common accessibility. They are widely applied for characterization of new instruments, materials and components designed to operate in harsh radiation environments either in space or in accelerators and particle physics experiments. In addition to running the exposure facilities we apply detection technologies from the particle and nuclear physics for novel instrumental developments in space. Our current activities are small and versatile radiation monitors for characterization of the solar system particle environments and hard X-ray polarimeters for measurements of polarized photons emitted during explosive events such as strong solar flares or gamma ray bursts.


PIF group operates a proton irradiation facility connected with the biomedical accelerator PROSCAN and an electron test facility utilizing secondary beams from the main PSI ring accelerator. In addition we offer rich test infrastructure based on radioactive sources and electron monochromators. Our facilities enable generating realistic particle spectra encountered at any potential orbit. PIF is a member if the European Component Irradiation Facilities ECIF supported by the European Space Agency.

Particle Physics Applications

First developments of radiation monitors resulted in industrial serial production. These instruments, Standard Radiation Environment Monitors SREMs, are already flying on several ESA satellites such as INTEGRAL, Rosetta, PROBA1 and Giove B (GPS). Our current activities in the field of radiation monitoring are twofold. In frame of the long-term industry and ESA collaboration we are developing the successor of SREM. This instrument called the Next Generation Radiation Monitor NGRM is planned to map the Earth radiation environment as e.g. a payload onboard of several meteorological satellites. In addition, we build the Radiation Hard Electron Monitor RADEM for study of the Jupiter radiation belts in frame of the ESA JUICE mission. We are also involved in development of the novel hard X-ray polarimeter POLAR. This instrument has already reached its Flight Model stage and is planned to be placed onboard of the Chinese Space Station TianGong2.
