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). 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 below -60° using a combination of the radiator and the peltier cooler. We have developed the engineering model (EM) of the MAXI/SSC. Combining with the EM electronics, we achieved the low readout noise (~5 e- rms) and a good energy resolution (150 eV at MnKα). We report the current status of the developments of the MAXI/SSC.
