Abstract

A high-temperature radiation source has been developed for the absolute calibration of diagnostic instruments for measuring electron cyclotron emission from high temperature plasmas. The source has a radiation area of Φ150 mm which is large enough to cover the spot size of the antenna radiation pattern (~Φ450 mm at the center of the JIPP T-IIU plasma) and can be heated up to 500 °C. The measured emissivity of the source is close to unity in the wavelength region between 0.5 and 5 mm.
