A high-speed baseline restorer for neutron flux detection in ITER

摘要

A neutron flux monitor (NFM) is a key diagnostic system in the International Thermonuclear Experimental Reactor (ITER), and may provide readings of a series of important parameters in fusion reaction processes. As a valuable part of the main electronics system of the NFM, the high-speed baseline restorer we designed is an important signal conversion plug-in which can restore the input signal baseline offset to a zero level, while keeping the output pulse signal waveform from the preamplifier basically unchanged.
