A 2000hyphen;channel intensified diode array detector has been developed for use with a 1hyphen;m normal incidence spectrometer. The detector has been operated over the wavelength region 300ndash;1700 Aring; with a readout interval of 20 ms to survey the spectrum of the DITE Tokamak. With this spectral coverage the resolution is sufficient (sim;0.1 Aring; in first order) to monitor rotational shear from simultaneous observation of a range of ion species. Additionally, by restricting the number of channels recorded, the detector has been used to examine details of individual line profiles more frequently allowing the observation of rapid (2 ms) evolution of plasmarsquo;s mass motion effects. We also report on the intensity calibration of the spectrometer and detector combination using a deuterium lamp over the range 1700ndash;1100 Aring;.
