The results of the application of p in 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 irridium 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 in 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 in diodes is considered. Such sensors are very convenient for online separated total dose measurements in mixed gamma-neutron radiation fields, as well as for radiation hardness testing of electronic components on irradiation facilities, and could be installed near the detector area of LHC. �� 1994 IEEE
