Abstract

Soft X-ray Imager (SXI) is a CCD camera onboard the ASTRO-H satellite which is scheduled to be launched in 2014. The SXI camera contains four CCD chips, each with an imaging area of 31mm× 31 mm, arrayed in mosaic, which cover the whole FOV area of 38' × 38'. The SXI CCDs are a P-channel back-illuminated (BI) type with a depletion layer thickness of 200 μm. High QE of 77% at 10 keV expected for this device is an advantage to cover an overlapping energy band with the Hard X-ray Imager (HXI) onboard ASTRO-H. Verification with engineering model of the SXI has been performed since 2011. Flight model design was fixed and its fabrication has started in 2012.
