Flight Calibration of the MAXI/SSC
Abstract
Monitor of All-sky X-ray Image (MAXI) is an astrophysical payload for the Japanese Experiment Module (Kibo) on the International Space Station (ISS) launched in July 2009. MAXI is designed for monitoring all sky in the X-ray band. MAXI consists of two X-ray detector systems: the Gas Slit Camera (GSC) and the Solid-state Slit Camera (SSC).
The SSC consists of two CCD cameras: each contains 16 CCD chips. The CCD chip has 1024 x 1024 pixels and covers 25mm square. The thickness of depletion layer is 70 μm. These CCD chips are cooled down to -60 degree using a combination of the radiator and the peltier cooler. During the initial check out phase of the SSC, we found that all 32 CCD's and peltier coolers are working correctly and have achieved a good energy resolution (150 eV in FWHM at Mn-Kα). We also found that Cu emission line originated from the collimator can be seen in all 32 CCD's. We report the current flight calibration status of the MAXI/SSC- Publication:
