We present results from a Bragg rotor spectrometer and refer to wide-ranging studies of intrinsic and injected impurity ions in the DITE Tokamak.The instrument has absolute calibration for flux and wavelength and can detect impurities at the part per million level in the band from 1 to 24Å. Monochromator and fast spectral survey modes, combined with a spatial scan facility, result in a versatile and powerful diagnostic tool.
