Paper Abstract

We have designed, built, and tested a low cost, flexible X- ray CCD camera for laboratory use to assist with the calibration of the Chandra x-ray Observatory High Resolution Camera (HRC). This CCD camera design will also serve as a prototype for future light opportunities. In this paper, we describe the design and performance of this camera, and present some sample data. For initial testing, we have purchased a commercially available EEV 30-11 CCD, but the camera can be modified to accommodate virtually any device in a minimal amount of time. We have achieved a readnoise of 3.5 electrons, and an energy resolution of 135 eV at Mn K(alpha) , with the EEV 30-11 device. This camera will be used extensively in the near future for HRC related calibrations.
