APPLICATION OF IONIZATION -TYPE SEMICONDUCTOR DEVICE FOR INFRA -RED DIAGNOSTICSYu.A. Astrov, Yu.A. Drozhbin,L.N. Portsel, V.E. Prokopenko, V.B. Semenov, Yu. P. TusovaAll -Union Research Institute for Optical and Physical Measurements, Moscow 103045, USSRThe problem of recording fast processes in IR spectrum remains an urgent one up till now. The authors of /1 -3/ proposed a principallynew device which they called ionization -type semiconductor system (ITSS). It features high sensitivity and rapid response in a broad spectralrange. The ITSS is a promising means for recording and measuring the space -time parameters of IR flash sources.The operating principle of the ITSS is based on control of the discharge current of a gas gap by means of an electrode made of
