Abstract

The design and application of a multichannel fiberoptic system for recording (MSR) of dynamic, spectral and energy characteristics of radiation sources in the range of 10^-10-10^-8 s is considered. Simultaneous recording of radiation characteristics in different areas of the object under study provides extensive information capabilities and ease of operation. The total number of fiber-optic channels is 12, of which 9 are designed to register the dynamics of radiation. The dynamics of the radiation is recorded by a developed multi-channel high-speed electron-optical camera with a resolution of 40 to 200 ps, depending on the type and length of the optical cable. The maximum resolution of the spectral equipment in the range of 500-700 nm is 0.06 nm. Transient processes in electrical and optical channels of radiation detection are considered. The possibilities of using MSR to study the dynamics of luminescence along the discharge channel in gases and semiconductors excited by sub-nanosecond pulses of an electron beam or an electric field are shown. During the studies the dynamics, spectrum and energy of the radiation were simultaneously recorded. The results of experiments and the possibilities of using MSR in the study of high-speed processes are discussed.
