The C IV (
= 6-7) spectral lines emitted from the JT-60U detachedplasmas were observed with a high-wavelength resolution spectrometer and theprofiles were analyzed with a PPP code. The analysis indicates that thespectral profiles were broadened with both the Doppler and the Starkeffects. From these effects, the electron temperature and density wereevaluated. Along the viewing chord for the X-point, the electron temperatureand density was determined to be 3 eV and 7
10
m
, respectively. These are similar to those determined from the intensity ratioof C IV lines (6.3 eV and 7.8 10 m, respectively). The high density plasma around the X-point was confirmed withthese independent methods.
