Abstract

A high temperature (T = 500°C) radiation source has been developed for the calibration of electron cyclotron emission measuring system on the JIPP T-IIU tokamak. The source has a heated area of (1)150 mm, and has the same emissivity as that of the microwave absorber Eccosorbe. The grating polychromator has been calibrated using the radiation source developed. The obtained electron temperatures agree with those by Thomson scattering within 10%.
