2D imaging X-ray spectrometer on WEST : results and technical challenges

Abstract : A new imaging X-Ray spectrometer has been installed, aligned and used on the WEST tokamak. A typical experimental spectrum is presented for each of the 3 interchangeable crystals, measuring respectively the Ar XVII, Ar XVIII and Fe XXV spectra. The instrument function exhibits a distortion for the Ar XVII spectrum, presumably due to the crystal splitting in 2 stripes and non-parallelism of the crystal layers. The Ar XVII and Ar XVIII spectra also display blends of unidentified spectral lines, presumably W lines
