Low-fringing CCD's: Improving Instrument Performance at ING
Abstract
The ING has recently integrated an E2V CCD44-82 red-sensitive CCD into a cryostat for use on the INT Intermediate Dispersion Spectrograph (IDS).
This is the latest in a series of red-sensitive low-fringing devices. At the WHT both ISIS and ACAM have already been fitted with these detectors.
The recently commissioned 2k x 4k pixel deep depletion low fringing device gives 3-4e noise, dark current \textless8e/hour and linearity \textless1\% up to 60kADUs.
This new low device (Red+2) shows very low fringing 1\% in the red rising to 2\% at 1000nm. The previous device (EEV10) has severe fringing, 3\% at 700nm rising to 30\% at 1000nm.
An E2V CCD231 4k by 4k pixel low fringing device has recently been received and is expected to be commissioned on WYFFOS during 2012.
