A Fission Product Detection System of the Magnetic Spectrometer

摘要

An electronic fission-product detection system with the remote control from an IBM PC computer in the WINDOWS-XP environment has been designed to detect fission products in the focal plane of the mass spectrometer placed in the horizontal channel of the VVR-SM research reactor at the Institute of Nuclear Physics, Academy of Sciences of Uzbekistan and used for studying fission of heavy nuclei induced by reactor neutrons. A 32-strip semiconductor detector is for the first time used for these purposes. The detection system is composed of modules mounted in a single housing. C8051F127 programmable microcontrollers with built-in ADCs, DACs, RAMs, and other units, are the basis of each module, which allows data on the spatial distribution of fission products, their quantity, and energy to be collected and transmitted to a remote computer.
