Scientific paper

X-ray interferometry has the potential for observations of unprecedented angular resolution and far reaching astrophysical consequences. I discuss general requirements for constructing x-ray interferometers. I then present three x-ray interferometer observatory concepts based on the Michelson stellar interferometer: two sub-milliarcsecond interferometers which can resolve nearby stellar coronae and jets in AGN's, and a sub-microarsecond resolution design which could resolve and measure the diameters and inclinations of accretion disks in AGNs and determine the orbital parameters of x-ray binaries. Two of the designs exploit the large angle reflection capabilities of multilayer mirrors. Optical interferometric techniques being developed for gravity wave beam detectors provide the necessary metrology. Tracking is performed by parallel optical interferometers. Observations of sources fainter than 0.1 of 3C273 and Capella should be possible. For the sub-microarsecond interferometer, a lunar platform is essential for providing a stable, kilometer-length baseline.
