Description
Summary:This paper describes the development and test of a radiation tolerant photodetector. This was accomplished by building a single stage photo multiplier tube with a physically small, dielectrically isolated, silicon photodiode array at the anode. In this device the optically generated photocurrent is multiplied by a much larger factor than is the photo-Compton current. Using matched "sighted" and "optically blind" diodes to differentiate the optical signal from the "common-mode" ionizing radiation photocurrent also contributes to radiation tolerance.
