Gamma spectrometer on the base of the DGDK detector, the BUS-2 input device and the AI-4096-3M analyzer on-line with the M-6000 computer

The modernized gamma spectrometer operating on-line with the M-6000 compUter is described. For improving the stability of the spectrometric complex operation a generator of stable amplitude developed on the base of the Bradley scheme is introduced into the input device. The results of measurements of temperature instability of the spectrometer energy scale have shown that it does not exceed 0.01%/deg C. Two methods of miscalculation account and random pulse superpositions in the electronic spectrometric channel have been experimentally investigated. It has been found that the method of normalization by the peak are of the stable frequency pulse generator allows to measure counting rates in total absorption peak with 1% accuracy at input loadings up to 10000 imp/s. The exposition mode by ''live'' time with correction is characterized by somewhat less accuracy. The energy resolution of the spectrometer on line of 1333 keV at a loading up to 30000 imp/s is less than 5 keV. A particUlar attention is given to the description of the connection channel of a modernized gamma spectrometer with distance detector location. The increased noise immunity of the connection channel and data transmission in a discrete form give the possibility of placing the detector at the 600 m distance from the analyzer. Functional flowsheets of the interface unit pulse analyzer with the M 6000 computer and connection unit of the analyzer with perforator are presented. Data transmission from the analyzer to the M-6000 computer at the 50 m distance from the analyzer is realized in the form of a 16-digit number
