A CCD spectrograph for the University of Toronto Southern Observatory in Chile
Abstract
A low-noise, glycol-cooled CCD has been installed on one of the Garrison classification spectrographs and tested using the 61-cm Helen Sawyer Hogg telescope of the University of Toronto Southern Observatory (UTSO) on Las Campanas in Chile. The spectrograph is small and would not be able to support the large liquid-nitrogen dewar used for the UTSO direct-imaging system. Operated in the MPP mode, the PM512 CCD has such low dark current that it can function successfully at -46 C, thus avoiding the need for a large dewar on the end of the spectrograph.
