All sky monitor (ISS) Two types of X-ray detectors viewing the sky through slit apertures: GSC: 12 proportional gas counters (2-30 keV). Effective
area of 6000 cm SSC: CCD camera, 32 CCD chips. Energy resolution: 135 eV FWHM at 5.9keV NEXT (Japan) NEXT Hard X-ray Telescopes (HXTs): use super mirrors to concentrate hard X-rays up to ~80 keV. Wide-band X-ray Imagers (WXI): upper-stage soft X-ray detector: thinned X-ray CCDs lower-stage hard X-ray detector: CdTe pixel detector Soft Gamma-ray detector (SGD): ultra-low background, high-sensitivity detector in soft gamma-ray band by
combining an active shield and a pixel detector. Soft X-ray Telescope (SXT) and Soft X-ray Spectrometer (SXS).
