Thermal and mechanical design and test of the CCD mount for the WEAVE spectrograph cryostats

Abstract:

WEAVE is the new multi-object spectrograph for the William Herschel Telescope on La Palma. The culmination of prime focus, the large number of fibers and the wide resolution range has required a stringent optical design, which in turn demands a spectrograph with tight positional tolerances and large final focal plane. To capture this focal plane each of the two cryostats has two e2v 6k x 6k CCDs mounted as a mosaic. As well as being cooled to 150K via liquid nitrogen, the positional tolera...
