MegaCam is the new wide-field imaging camera currently being built for the new prime focus of the 3.6m Canada-France-Hawaii Telescope. among all the challenges imposed by the ambitious specifications of MegaCam, there is the CCD Controller. We chose to realize a new highly integrated CCD Controller and to implement some other original solutions. This paper presents the solutions we retained.

The CFH12K is a 12k * 8k CCD mosaic camera for the Canada-France-Hawaii Telescope (CFHT), a 3.6m telescope located on Mauna Kea, Hawaii. The CFH12K is comprised of twelve 4k * 2k thinned backside-illuminated CCDs, arranged in a close-packed array of two rows each containing six CCDs. Located at the CFHT Prime Focus (f/4.2), the CFH12K provides a 42 by 28 arcminute field-of-view, 0.206 arcsecond per pixel sampling, with a resulting data file of more than 200Mbytes per image. The camera has been designed to exploit the exceptional wide-field imaging capability provided by the CFHT. At the time of it's commissioning in January 1999, the CFH12K is the largest thinned close-packed CCD mosaic in astronomy. This paper describes the system architecture, and some of the relevant issues associated with the construction, evaluation, and operation of very large mosaic cameras. Emphasis is given to system design issues, illustrating the CFH12k as part of a larger system: the CFHT.

This paper presents the design, construction and performance parameters for the optical detector systems for UVES (1), the echelle spectrograph for the UT2 Kueyen Telescope at the ESO paranal. A general overview at system level with a description of the individual components is also given. Emphasis is given on the CCD detectors and their performance. The two arms are equipped with large science CCD detectors, one single chip in the blue arm and a mosaic of two in the red. The blue CCD is a 2K x 4K, 15 mu m pixel size thinned EEV CCD-44. The mosaic in the red arm is made of an EEV chip of the s ame type and an MIT/LL CCID-20 chip (2K x 4K), which features a higher NIR QE and reduced fringing for the redder part of the spectral range. The read noise archived with th CCDs at the telescope is less than 2 electrons for the EEV CCDs and less than 3 electrons for the MIT/LL CC at a readout speed of 50 kpixel/sec/port. The systems offer a variety of readout modes, binning options and readout speeds up to 625 kilopixel per second per port with linearity variations better than 1
