Abstract

Deuterium experiment on the Large Helical Device (LHD) is now being planned at the National Institute for Fusion Science. The fusion product diagnostics systems currently considered for installation on LHD are described in this paper. The systems will include a time-resolved neutron yield monitor based on neutron gas counters, a time-integrated neutron yield monitor based on activation techniques, a multicollimator scintillation detector array for diagnosing spatial distribution of neutron emission rate, 2.5 MeV neutron spectrometer, 14 MeV neutron counter, and prompt γ-ray diagnostics.

摘要

日本国立聚变科学研究所目前正在计划在大型螺旋装置（LHD）上进行氘实验。本文介绍了目前考虑安装在LHD上的聚变产物诊断系统。这些系统将包括基于中子气体计数器的时间分辨中子产额监测器、基于活化技术的时间积分中子产额监测器、用于诊断中子发射率空间分布的多准直器闪烁探测器阵列、2.5兆电子伏中子谱仪、14兆电子伏中子计数器以及瞬发γ射线诊断装置。
