中性粒子分析仪的研究现状
Present Status of Neutral Particle Analyzer
摘要
Abstract
The neutral particle analyzer(NPA)serves as a crucial diagnostic tool in Tokamak devices,providing valuable insights in plasma physics with wide-ranging applications.By accurately measuring neutral particles that escape from the plasma,the NPA allows for the retrieval of key plasma information,including ion temperature,high-energy particle spectra,and hydrogen isotope ratios.Since its introduction as the first NPA,originally known as a neutral atom analyzer,in the 1960s,this diagnostic instrument had significantly advanced over the past six decades,resulting in the development of various NPA types.In order to address fast ion physics research on HL-3 device,Sichuan University and Southwestern Institute of Physics have collaboratively developed a tandem parallel electromagnetic field structure NPA(E//B NPA)based on LYSO+SiPM detectors.This E//B NPA has been successfully installed on the HL-3 device,enabling the accurate measurement of the high-energy deuterium neutral particle spectrum during plasma discharge experiments.This achievement establishes a strong technical foundation for future neutral particle diagnostics and fast ion research on the HL-3 device.关键词
