Test Benches Facilities For Paucam: Ccds & Filters Characterization

The PAUCam [1] is an optical camera with a 18 CCDs (Hamamatsu Photonics K. K.) mosaic and up to 42 narrow-and broad-band filters. It is foreseen to install it at the William Herschel Telescope (WHT) in the Observatorio del Roque de los Muchachos, Canary Islands, Spain. As required by the camera construction, a couple of test bench facilities were developed, one in Madrid (CIEMAT) that is mainly devoted to CCDs read-out electronics development and filter characterization [2], and another in Barcelona (IFAE-ICE) that has as its main task to characterize the scientific CCDs in terms of Dark Current, CTE, QE, RON and many other parameters demanded by the scientific performance required.The full CCDs characterization test bench layout, its descriptions and some optical and mechanical characterization results are summarized in this paper.
