Abstract
The New Hard X-ray Mission (NHXM) is conceived to extend the grazing-angle reflection imaging capability up to energy of 80 keV. The NHXM payload consists of four telescopes. Three of them have at their focal plane identical spectral-imaging camera operating between 0.2 and beyond 80 keV, while the fourth has a X-ray imaging polarimeter. The spectral-imaging cameras are constituted by two detection layers: a Low Energy Detector (LED) and a High Energy Detector (HED) surrounded by an Anti Coincidence (AC) system. Here we will present the preliminary design and the solutions that we are currently studying to meet the top level system requirements of these cameras.
