Microchannel plate imaging detector on Chandra (PI: S.Murray, SAO) which contains two arrays: a square for imaging (HRC-I) and a narrower strip (HRC-S). HRC-S is primarily for readout of the diffraction gratings, especially LETG, and for high time resolution observations (using the central element only).
