A tunable crystal diffraction telescope for the International Space StationA focusing gamma ray telescope is proposed for use onboard the International Space Station. It consists of a tunable crystal diffraction lens which focuses gamma rays onto a small array of germanium detectors located on an extendable boom. While the weight of such an instrument is less than 500 kg, it features an angular resolution of 15 arcsec, an energy resolution of 2 keV and a 3 sigma sensitivity of the order of 10(exp -7) photons/sq cm sec for any individual narrow line at energies of between 200 and 1300 keV. The scientific potential of such a telescope is discussed. The principles of a diffraction lens and a tunable diffraction lens are described.
