Paper Abstract

We have developed detectors design for high resolution spectroscopic imaging for the EUV spectrometer on the ORFEUS-SPAS mission. The detectors employ spherically curved microchannel plates and a delay line read out system. We present results from the testing and calibration of the detectors prior to their integration into the spectrometer. The design, MCP preconditioning, and imaging characteristics are discussed for 2 rectangular spectral detectors and for the fine guidance detector. Each spectral detector achieves a 30 X 100 micrometers FWHM resolution element size over a 95 mm X 25 mm anode format with good linearity (< 30 micrometers ) in the spectral direction. The fine guidance detector, used for drift corrections, achieves good resolution and will meet the necessary centroiding requirements.
