Active multichannel scintielectronic new-generation detectors based on zinc selenide

Properties are reported of new types of active module 32- channel scintielectronic detectors of 'scintillator- photodiode' type with step h equals 0,8 mm for low-energy x-ray introscopic systems. As scintillator, 'fast' modification of crystal ZnSe(Te) was used in three variants: individual single crystal elements for each channel, a single crystal plate common for all channels, and a small crystalline composite plate with grain size d equals 0,25 divided by 0,5 h. Active detectors based on ZnSe(Te) scintillators and active 32-channel photoarrays with combined pattern of preliminary transformation and sequential sampling ensures x-ray sensitivity of 0,8 divided by 2.
