Description
FRIB is one of the premier rare-isotope beam facilities, with the capability of producing a majority (approximately 80 percent) of the isotopes predicted to exist from oxygen to uranium, and beam energies of 200MeV/u. With the increase in beam power from the present 5kW to the planned 400kW, FRIB experiments are about to enter a new era which requires the operation of particle detectors at unprecedented high rates of low-mass proton-rich nuclei. Full functionality of such detectors over the long time required by experiments in a harsh radiation environment is of prime concern. A summary of aging phenomena in the Advanced Rare Isotope Separator (ARIS) detectors for beam diagnostics, including Parallel Plate Avalanche Counters (PPAC) and plastic scintillation detectors for time-of-flight measurements, are presented.
