40 CCDs of the MegaCam wide-field camera: procurement, testing, and first laboratory results

The 40 CCDs produced at Marconi Applied Technologies (hereafter MAT/EEV) are dispatched at CEA to be tested and characterized before being inserted into the MegaCam camera mosaic. We describe here briefly our CCD test bench, the measurements we perform with it and the results obtained so far. A model has also been developed to interprete the quantum efficiency results.
