IntroductionPaul Scherrer Institute (PSI) constructed Proton Irradiation Facility (PIF) for testing of components and electronic parts used in harsh radiation environments. The facility is designed in a user friendly manner and is commonly available for experiments. It enables generating of realistic proton spectra encountered either in space at any potential orbit or during experiments in particle accelerators research institutes.
Radiation hazards - demand for ground testsThe proton environment either in space or at the accelerator research test sites can have a detrimental effect on semiconductor components and other materials. The ability to simulate this environment in well controlled laboratory conditions enables projects to take this hazard into consideration in the design stage. For space missions, depending on the spacecraft orbit and duration, the spectra will differ. One of the principal advantages of the PIF is its ability to reproduce them in a reliable manner. The PIF has been originally implemented to investigate:
· Radiation hardness of the new electronic products
· Single Event Effects such as upsets, latch-ups or transients
· Properties of radiation monitors for space and laboratory applications
· Basic mechanics of radiation effects in semiconductors
· Space radiation environment by on-earth simulations
User lab leading featuresThe facility allows conducting research on radiation induced effects in electronics and devices. It not only enables experiments with realistic space proton environment but also provides mono-energetic beams for radiation hardness tests of materials. PIF is used extensively by the space community as well as by research teams in other disciplines. Our long-term experience with industries and space agencies provides extra benefits in field of applied science and technology. Several experiments in physics as well as testing and calibrating of modern particle detectors and radiation monitors have been already performed. A wide range of applications is feasible due to elementary design aspects assuring:
1. Broad range of energies and intensities of the proton beam
2. Experiment adaptable monitoring of flux and dose
3. Fast and uncomplicated experimental setup
4. Transparent operating procedure
5. User friendly data acquisition system
6. Flexibility towards customers needs
Operation and irradiation experimentsAs a prime user the PIF is available for irradiation experiments in the test area of biomedical accelerator. The tests are performed for space and accelerator community such as ESA or CERN and their related users. The facility is also commonly available for applied research conducted by external laboratories, universities and industry. All PIF irradiations are performed in parasitic mode after biomedical therapy beam blocks. Because day shifts are reserved for biomedical applications, the irradiations are performed mostly during weekends and at short night shifts.
Short-duration experiments require an irradiation request and order. Project extended over longer period or with substantial demand for the beam time need an approval by the Research Committee and PSI Technology Transfer Office. The PSI beam production schedule for the next period can be found at Accelerator Physics and Development Division beam production page. The schedule for the next week is also available. Please look at PROSCAN part of the program.
