Titanium full Kα spectra have been measured using a wide-band crystal spectrometer in lower-hybrid current drive experiments and increase in the total Kα counts has been observed at electron densities below 7×1012cm−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/Iwand 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.
