摘要
Abstract
Neutron dose monitoring plays an important role in the field of radiation protection.At present,the monitoring of both nuclear facilities and neutron dose equivalent around the particle accelerator uses the gas detector,with the core of 3He proportional counter,as its dosimeter.To determine the performance of the proportional counter is the base of accurate measurement of neutron dose.After analyzing its performance such as the operational principle,output signal and time resolution,this experiment determined parameters such as counter mechanism,pulse-amplitude modulation (PAM),dead time and working voltage.关键词
