2016年底，红外成像热辐射计（IRVB）的原型在Alcator C-Mod托卡马克上成功进行了测试。IRVB方法通过测量一个薄的~ 2 μm的Pt吸收体的温升来解释等离子体辐射的功率，该吸收体放置在环面真空中，并使用针孔相机暴露在等离子体光子发射的全光谱中。安装在C-Mod上的IRVB观察了核心等离子体的极向截面，并观察了欧姆和离子回旋频率范围（ICRF）加热等离子体。总结了IRVB的总辐射功率和轴上发射率的分析，并与电阻式测辐射热计和AXUV二极管的数据进行了定量比较。IRVB的结果显然在两个因素之内，但需要额外的努力才能用于完全支持动力排气研究。研究表明，IRVB不受ICRF的电磁干扰，而ICRF会强烈影响C-Mod的电阻式测辐射热计。总结了台式校准的结果，包括一种适用于IRVBs的新型温度校准方法。
A prototype of an infrared imaging bolometer (IRVB) was successfully tested on the Alcator C-Mod tokamak at the end of its 2016 campaign. The IRVB method interprets the power radiated from the plasma by measuring the temperature rise of a thin, ∼2 μm, Pt absorber that is placed in the torus vacuum and exposed, using a pinhole camera, to the full-spectrum of plasma's photon emission. The IRVB installed on C-Mod viewed the poloidal cross section of the core plasma and observed Ohmic and ion cyclotron range of frequency (ICRF)-heated plasmas. Analysis of total radiated power and on-axis emissivity from IRVB is summarized, and quantitative comparisons made to data from both resistive bolometers and AXUV diodes. IRVB results are clearly within a factor of two, but additional effort is needed for it to be used to fully support power exhaust research. The IRVB is shown to be immune to electromagnetic interference from ICRF which strongly impacts C-Mod's resistive bolometers. Results of the bench-top calibration are summarized, including a novel temperature calibration method useful for IRVBs.
