9 July 1998 New generation CCDs: applications and performance results
Author Affiliations +
Within the last few years several manufacturers have been producing the 'next generation' of scientific CCDs. These devices have small pixels (approximately 15 micrometers), high UV and broad-band spectral response (greater than 80%), very low readout noise (less than 4 e- rms), large format (2048*4096) and close butting capability. We present examples of recent data taken on the WHT (at the Roque de los Muchachos Observatory, La Palma) obtained from one such device -- the EEV CCD42 array. The detector has been used for spectroscopy and direct imaging with excellent results. Design and performance details, as well as various special operational modes will be discussed. This device has been adopted for scientific imaging on the Gemini telescopes, as well as several other major observatories -- and so these first operational results should demonstrate the power of these new sensors. Variants of the CCD42 design are now being made to yield slightly different architectures and packaging options. We will compare predicted with actual performance, and discuss characteristics and applications of this new sensor.
