Abstract
ELMER is a multi-purpose instrument for the GTC designed for both, imaging and spectroscopy in the visible range. The detection subsystem consists of a single E2V Technologies CCD44-82 detector mounted in a LN[2] cooled CCD camera and a SDSU-II CCD controller with parallel interface. The design including the low-noise fan-out electronics has been kept flexible to allow alternatively the use of MIT/LL CCID-20 detectors. We present the design of the CCD camera and first test results.
