Abstrakti

The Chandrayaan-1 XSM ground calibrations are introduced. The aim of these calibrations was to characterize the performance of XSM, which enables a reliable spectral analysis with the solar X-ray data. The calibrations followed an improved procedure based on our experience from the SMART-1 XSM. The most important tasks in the calibrations were determination of the energy resolution as a function of the photon energy and mapping of the detector sensitivity over the FoV (Field of View) of the sensor. The FoV map was needed to determine the obscuration factor corresponding to various pointings with respect to the Sun. We made also a sensitivity comparison test between the Chandrayaan-1 XSM FM (Flight Model) and SMART-1 XSM FS (Flight Spare). The aim of this test was to link the new XSM performance to a performance of an already known and tested former instrument. We also performed a simple test to determine the pile up performance, and one specific test tailored for the operation of the new version of XSM. Also the first experiences on the in-flight operation are briefly described. (C) 2009 Elsevier B.V. All rights reserved.
