“…There found a deviation from the straight line at around and above the Si K-edge. Similar deviation was found in the XIS for Astro-E1, but the amount of deviation was reduced if we refine the data reduction, for example, taking into account of the detailed pulse profile including the tail structure 1,2 . Further examination of such effect for the Astro-E2 XIS results is needed The slope of the Ex-PH relation represents the gain of the XIS system.…”

“…The design of Astro-E2 XIS is basically the same as that for Astro-E1 described in Hayashida et al 1,2 The system consists of four X-ray CCD cameras, analog electronics (AE), and digital electronics (DE). Each CCD camera has one frame-transfer type CCD chip manufactured by MIT Lincoln Laboratory.…”

“…The soft X-ray calibration system and its usage for Astro-E1 XIS calibrations were described in series of papers 1,2,5,6 . The system consists of a soft X-ray source, Manson model 2 ultra soft X-ray source, and a grating spectrometer by Hetrick Science, and a chamber in which a CCD camera and/or a gas proportional counter are installed.…”

We present the current status of soft X-ray calibration of X-ray CCD cameras, X-ray Imaging Spectrometer (XIS), onboard Astro-E2. We perform soft X-ray calibration of four front illuminated (FI) CCD cameras and two back illuminated (BI) CCD cameras, among which four cameras will be selected to be installed on the satellite. The calibration aims to measure the quantum efficiency and redistribution function of the CCDs as a function of incident Xray energy. A soft X-ray spectrometer is used to measure these items. In addition, we employ a gas proportional counter and an XIS engineering unit as reference detectors for the quantum efficiency measurement. We describe how we calibrate the absolute quantum efficiency of the XIS using these instruments. We show some of the preliminary results of the calibration including quick look results of BI CCD cameras.

We have implemented a Monte Carlo algorithm to model and predict the response of various kinds of CCDs to X-ray photons and minimally-ionizing particles and have applied this model to the CCDs in the Chandra X-ray Observatory's Advanced CCD Imaging Spectrometer. This algorithm draws on empirical results and predicts the response of all basic types of X-ray CCD devices. It relies on new solutions of the diffusion equation, including recombination, to predict the radial charge cloud distribution in field-free regions of CCDs. By adjusting the size of the charge clouds, we can reproduce the event grade distribution seen in calibration data. Using a model of the channel stops developed here and an insightful treatment of the insulating layer under the gate structure developed at MIT, we are able to reproduce all notable features in ACIS calibration spectra.The simulator is used to reproduce ground and flight calibration data from ACIS, thus confirming its fidelity. It can then be used for a variety of calibration tasks, such as generating spectral response matrices for spectral fitting of astrophysical sources, quantum efficiency estimation, and modeling of photon pile-up.
