Abstract
A space- and time-resolving EUV spectrometer (SIRS) for fusion plasma impurity diagnostics is in operation at the DIII-D tokamak at GA Technologies in San Diego. An array of three modified Fairchild CCD cameras behind an EUV-to-visible converter/intensifier is used to record spatially resolved spectra in the 50 to 370 A range. Modifications and extensions to the Fairchild camera electronics allow a wide range of spatial binning on the CCDs and 2 to 50 ms time resolution, as well as computer control of the image format and timing. The CCD images are digitized and stored in buffer memories for computer acquisition. This paper briefly describes the spectrometer and the microchannel plate intensifier detector. The design of the imaging electronics is presented, along with the modifications necessary to obtain good flexibility and imaging quality. Results from photometric calibration work are presented.
