High-Pressure Xenon Detector in Nuclear Radiation Measurement System

摘要

With its excellent energy resolution and good temperature characteristics, high-pressure xenon detectors are widely used in extreme measurement environments such as high temperature and strong radiation. However, the energy resolution of the energy spectrum of the high-pressure xenon detector will be reduced or even distorted in a high-decibel noise environment. In order to better understand the noise sensitivity of high-pressure xenon detectors, this paper summarizes and analyzes the principle, development process and research status of high-pressure xenon detectors based on the literature on high-pressure xenon detector structure and performance at home and abroad. The study found that for the problem of baseline drift caused by the noise sensitivity of high-pressure xenon detectors, the traditional baseline restoration algorithm cannot effectively play a role. The adaptive baseline restoration method should be able to overcome this problem.
