Paper Abstract

For the 4.2 m William Herschel Telescope (WHT) to be erected at the Roque de los Muchachos Observatory on La Palma in the Canary Islands, the Netherlands Foundation for Radio Astronomy has developed a conceptual prototype integrated CCD controller in cooperation with the Royal Greenwich Observatory. It has been demonstrated that preamplifier noise limited system performance of 5 rWviliz. can be obtained with a compact low power controller that uses switched mode power supplies throughout. This performance has been realized by applying a differential preamplifier with balanced outputs between the CCD in the cryostat and the correlated double sampler in the controller, realizing over 100 dB common mode rejection. A complete system to drive two independent heads simultaneously each with either a large CCD or an array of four small chips can be realized into a small crate using single height long Eurocard modules and dissipate about 50 W.
