Description

A new soft x-ray pulse height analyzer (PHA), based on a Silicon Drift Detector (SDD) linear array consisting of 15 SDD detectors, has been installed in the HT-7 tokamak. The energy resolution of 150-180 eV at photon energy of 6 keV is achieved for the SDD with Peltier cooling. The effective time response of the SDD PHA is 50 ms. The profiles of electron temperature and the intensity of metallic impurities can be obtained with a spatial resolution of 3 cm. The performance and first experimental results from the new PHA system are presented
