红外成像视频测辐射热计（IRVB）是测量等离子体聚变装置多维辐射剖面的一种强有力的诊断仪器。在大型螺旋装置（LHD）中，安装了四个具有不同视场的IRVB，以使用层析成像技术重建三维轮廓。为了在不久的将来将测量应用于LHD中使用氘气的等离子体实验，应通过定期的原位校准测量来考虑中子辐照对IRVB箔的热特性的长期影响。因此，在本研究中，设计了一个现场校准系统。
The InfraRed imaging Video Bolometer (IRVB) is a powerful diagnostic to measure multi-dimensional radiation profiles in plasma fusion devices. In the Large Helical Device (LHD), four IRVBs have been installed with different fields of view to reconstruct three-dimensional profiles using a tomography technique. For the application of the measurement to plasma experiments using deuterium gas in LHD in the near future, the long-term effect of the neutron irradiation on the heat characteristics of an IRVB foil should be taken into account by regular in situ calibration measurements. Therefore, in this study, an in situ calibration system was designed.
