AB - GERMANIUM RADIATION COUNTERS AS CHARGED-PARTICLE SPECTROMETERS S. M. Ryvkin, V. V. Peller, UDC 539.1.074.55 N. B. Strokan, V. P. Subashieva, N. I. Tisnek, and V. K. Eremin The usual application of germanium counters is in 7-ray spectrometry. Ge(Li)-counters have been used with success, however, in charged-particle spectrometery [1]. In comparison with silicon, german- ium has a greater retarding capability and a smaller mean energy of formation of electron-hole pairs. In the present note we communicate the results of some experiments in which germanium radiation counters were used to determine the energy of charged particles [2-4]. Such counters, as opposed to Ge(Li)-detectors, can function stably at room temperature and do not require to be permanently cooled. The resolution R of radiation detectors depends on the donor impurity concentration ND in the initial ger- manium. For presently attainable values of N D ~ 5 9 1022 cm -3 it is possible to achieve for y-quanta a re- solution R ~< 1% in a working region d = 5 mm [4].* However, if ionization occurs near the p contact and the holes have to move through a distance less than 1 ram, the resolution can be expected to improve great- ly (in
