1,018,402. Measuring radiation intensity. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 18, 1962 [May 9, 1961], No. 16856/61. Heading G1A. [Also in Division H1] A radiation detector consists of a plurality of superimposed PN junction or surface barrier devices which are air-spaced or held apart by insulating spacers, has means for applying a reverse potential bias to each of the junctions or barriers, and has means for detecting radiation-induced discharge through the junctions or barriers. The devices are made and biased to such an extent that the depletion region associated with the junction or barrier reaches as much of the semi-conductor wafer as possible short of breakdown. A voltage pulse proportional to "particle" energy is obtained from the detector provided that the "particle" is absorbed in the device-linearity of response is therefore ensured for high energy "particles" by suitably increasing the number of devices used in the stack. The devices in the stack may be connected in series or in parallel.
