Abstract
The Atomic Energy Commission has set up a laboratory dedicated to the calibration of x-ray cameras mainly used in the Laser MégaJoule Facility in the Bordeaux region of France. Thanks to a double crystal monochromator specifically designed to perform such calibration, we calibrated a thinned, back-illuminated x-ray CCD manufactured by Roper Scientific Inc. over the 2.2-8.9keV spectral region. Quantum efficiency results are in good agreement with those of previous works. To explain slight differences, we studied the difference between monochromatization methods performed either using a crystal monochromator or filters. Results showed that the latter method appears to be too dependent on the x-ray source parameters to perform accurate and relevant calibration on x-ray cameras.
