Abstract
A low-noise, glycol-cooled CCD has been installed on one of the Garris on classification spectrographs and tested using the 61-cm Helen Sawye r Hogg telescope1 of the University of Toronto Southern Observatory (U TSO) 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 su ch low dark current that it can function successfully at -46-degrees-C , thus avoiding the need for a large dewar on the end of the spectrogr aph.
