研制了一套用于测量2058.130 nm He I 2S-2 P辐射跃迁的近红外光谱仪。对焦距为35 cm、F数为3.8的Czerny-Turner光谱仪进行了改进，使其能够通过安装256通道InGaAs线性图像传感器来测量NIR区域。在MAP-II偏滤器模拟器中测量的2 P状态中的人口在空间分布中表现出显着的加宽，与其他状态相比，这表明共振态的辐射俘获效应。
A near-infrared (NIR) spectrometer system intended to measure the He I 2S-2P radiative transition of 2058.130 nm was developed. A Czerny–Turner spectrometer with a focal length of 35 cm and an F-number of 3.8 is modified to give it the ability to measure the NIR region by installing a 256-channel InGaAs linear image sensor. The population in the 2P state measured in the MAP-II divertor simulator exhibits a significant broadening in the spatial distribution, compared with the other states, which indicates the effect of radiation trapping for the resonant state.
