Abstract

The X-ray Imaging Spectrometer (XIS) on the Astro-E2 mission contains X-ray CCDs fabricated at MIT Lincoln Laboratory. We present results from CCD subassembly calibration of these detectors. Absolute detection efficiency and spectral resolution in the 0.3-10 keV band are presented for four front-illuminated and two back-illuminated flight candidate devices. In addition, we characterize the charge injection capabilities of these devices. The quantum efficiency measurements have been used to model the various dead layers in the gate structure and to constrain the depletion depth of the detectors. Noise levels of 2 electrons, RMS, and spectral resolution better than 50 eV (FWHM) at 525 eV have been achieved. The small but measurable charge transfer inefficiency (less than 1e-5 per transfer at 5.9 keV) of these devices has been characterized as a function of X-ray energy.
