The Joint European Torus (JET) gamma-ray camera has been recently upgraded with the installation of new gamma-ray detectors, based on LaBr3(Ce) scintillation crystals, which add spectroscopic capability to the existing system allowing measurements with good energy resolution (5% at 0.622 MeV), a dynamic range from hundreds of keV up to about 30 MeV, and high counting rate capabilities of MCps. First gamma-ray measurements during the C38 campaign of the JET have been successfully carried out, in particular, in D–3He plasmas from three-ion ion cyclotron resonance heating experiments, where the detection of 16.4 MeV γ-rays from D + 3He → γ + 5Li reactions with the gamma-ray camera upgrade allowed determining the spatial profile of alpha particles born in D + 3He fusion reactions.

使用升级的 JET 伽马射线相机对 D-3Heα 粒子源进行首次空间分辨测量
联合欧洲环面 (JET) 伽马射线相机最近升级，安装了基于 LaBr 3 (Ce) 闪烁晶体的新型伽马射线探测器，为现有系统增加了光谱能力，允许以良好的能量分辨率进行测量（ 5% at 0.622 MeV)，从数百 keV 到大约 30 MeV 的动态范围，以及 MCps 的高计数率能力。JET C38 活动期间的首次伽马射线测量已成功进行，特别是在来自三离子离子回旋加速器共振加热实验的D- 3 He 等离子体中，其中检测到来自 D + 3的 16.4 MeV γ射线他 → γ + 5伽马射线相机升级的锂反应允许确定在 D + 3 He 聚变反应中产生的 α 粒子的空间分布。
