Abstract
1,058,754. Radiation detection system. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 21, 1964 [May 2, 1963], No. 17386/63. Heading G1A. A detector for gamma or X-ray spectroscopy by pulse height analysis consists of two solid state detector units receiving the same radiation but formed of elements having different atomic numbers. The relative thickness of the sensitive regions of the two units are chosen such that substantially equal Compton effects are produced. The electrical outputs of the two units are subtracted so that the continuum of pulse heights produced by Compton scattering is cancelled out and only discrete pulse height signals due to photo-electric and pair production effects remain. In a preferred embodiment the units are reversebiased p-i-n junctions of silicon and germanium respectively, the thickness of the sensitive region of the silicon unit being twice that of the germanium unit. The two units are followed by separate amplifiers with gains adjusted to match the pulse heights. As shown in Fig. 3 these amplifiers may be arranged to feed memory circuits for identical consecutive intervals of time through gates controlled by a free running oscillator. The signals stored in the memory circuit for the time being are subtracted and investigated by means of a pulse height analyzer.
