To provide high quality Doppler images of a few bright stars in the field we envisage a small spectrometer dedicated to the CIV and NV lines. These optically thin lines are well suited to Doppler imaging. The collimated beam is dispersed by a primary grating, and a second camera grating in additive dispersion forms an image on the detector. The detector of choice for this instrument comprises a micro-channel plate intensifier tube with a spiral anode readout (Lappington et al. 1990, 1991, Breeveld et al. 1992). Such detectors are now in operation on the Extreme Ultra Violet Explorer, and are also planned for instruments on XMM and Spectrum-X. An image rotator is used to reduce source confusion by suitably arranging the target field on the detectors. The zeroth order reflection from the primary grating is focussed on to third detector in order to compensate, in real time, for pointing drifts.
