Abstract :
The results of the application of p-i-n and MOS dosimeters in the PS-ACOL Irradiation Facility (PSAIF) at CERN for separate measurements of gamma dose and fast neutron fluences are presented. The mixed gamma-neutron field was due to 26 GeV protons hitting an iridium target, yielding an instantaneous dose rate of approximately 3.105 Gy/s. Good agreement with calibration curves is found for MOS in a 60Co gamma source as well as for p-i-n sensors in a neutron reactor spectrum with mean energy of 1 MeV. Experimental results from PSAIF are presented and pulse current injection annealing of p-i-n diodes is considered. Such sensors are very convenient for on-line separated total dose measurements in mixed gamma-neutron radiation fields, as well as for radiation hardness testing of electronics. Components on irradiation facilities, and could be installed near the detector area of the LHC
