Abstract
The ROSAT (Roentgen Satellite) observatory was launched 1990 June 1, with a microchannel- plate-based high resolution imager (HRI) as one of the focal plane instruments of its primary soft x-ray telescope. Exhaustion of the gas supply for ROSAT's other focal-plane detector has left the HRI as the sole instrument for continuing the program of celestial soft x ray observations. The long-term behavior of the HRI is presented, with descriptions of imaging performance, quantum efficiency and gain stability, spectral resolution, UV response, and background characteristics.Keywords
