Abstract
We have developed a time-resolved two-dimensional temperature monitoring system using shortwave infrared (SWIR) detection scheme for a nanocrystalline diamond foil under intense hydrogen ion beams with 1.4 MW average power at 1.0 GeV energy in harsh radiation environment. The optical system composed of a light collecting reflective telescope, dichroic and bandpass filters, SWIR and visible CMOS cameras combined with PIN photodiodes and image sampling pinhole mirrors. It receives thermal radiation located at 40 m from the measurement location. The optical design, optical calibration of the system with high temperature blackbody source, measurement results based on two-dimensional temperature mapping and uncertainties will be presented.
