AN EVALUATION OF CADMIUM SULFIDE AS A NUCLEAR RADIATION DETECTOR (thesis)

OSTI ID:4705246
Solid state radiation detectors were constructed using crystal platelets of CdS. Both intrinsic and p-n junction detectors were made and evaluated. Although alpha particles were detected by both types of detectors, the mobility- lifetime product of the charge carriers resulted in the pulse response not being proportional to the energy of the incident particle. The best experimental value for the mobilitylifetime product in CdS was 2.6 x 10/sup -6/ cm/volt for the electrons and 2.1 x 10/sup -6/ cm/sup 2//volt for the holes. Also an experimental value of 5.2 ev dissipated per hole-electron pair formed was determined. A resolution of 6.8% was obtained with one detector. Other phenomena such as the trapping of the charge carriers and the ionization of neutral impurity atoms also were evident in the crystal. (auth)
