TWO-CRYSTAL SCINTILLATION SPECTROMETER WITH PULSE SUMMATION (in Russian)
A description is given of a gamma -ray scintillation spectrometer, working on the principle of the summation of pulse amplitudes from two detectors. The radiation from the source being tested must fall on the crystals of both detectors, which are located near one another. To detect radiation of given energy E/sub gamma / those photons are used which cause the Compton effect in one of the two crystals and the scattered quantum is absorbed in the second crystal by the photo-effect. In this case the amplitude of the pulse from the first detector is proportional to the energy of the scattered photon, which is E/ sub gamma /-E/sub e/. By electric summation of the amplitudes of both pulses we obtain a pulse having a final amplitude E/sub gamma /. The advantages of the summation spectrometer are thus the great efficiency in a broad energy region with simultaneous preservation of good resolution and the linearity of the spectrum. These properties, together with the great purity of the spectrum, give summation spectrometers priority over other types of multicrystal spectrometers. (auth)
