NONTHERMAL X-RAY SPECTRA FROM THE JIPPT-IIU TOKAMAK

Abstract
Titanium full Kα spectra have been measured using a vide-band crystal spectrometer in lover-hybrid current drive experiments and increase in the total Kα counts has been observed at electron densities below 7x1012cm-3. Highly resolved titanium He-like spectra have been also measured using a high-resolution crystal spectrometer to obtain electron temperature with intensity ratio of Is/Iw and ion temperature with w line broadening. The results show that the intensity ratio has remarkably high values and the narrowing of the w line is occured at ohmic phase. The production of suprathermal electrons in JIPPT-IIU is described with nonthermal x-ray spectra.
