A TWO DIMENSIONAL, 1024-CHANNEL PULSE HEIGHT ANALYZER (DMA-1024) (in Russian)
Although the amplitude distribution of nuclear radiations can be determined by multichannel analyzers, quite often the available instruments do not suffice as 2 correlated nuclear events must be investigated. Such a problem requires an analyzer the channels of which are able to determine the distribution of coincidences of 2 electrical pulses from 2 correlated particles or quanta as a function of the energy or the time-of-flight of the particles. Such a spectrum is defined by a three dimensional surface. For 2 correlated events the spectrum may be defined by a two dimensional system using a two dimensional analyzer. Such an instrument, provided with 1024 channels was developed for pulse-height determinations. It contains a recording block and 2 identical sorting devices, recording only the coincidence pulses from the detectors. A ferrite core memory device is used. The channels are displayed in X--Y matrices (32 x 32 = 1024). The dead-time of the instrument is about 150 microsec. A two dimensional spectrum of the gamma radiation of Co/sup 60/ is presented.
