Abstract

In a recent balloon flight on October 6-7, 1995, the Caltech coded aperture Gamma-Ray Imaging Payload (GRIP-2) imaged numerous fields in the Galactic plane and center in the 25 ke V - 600 ke V energy band. GRIP-2's large phoswich detector (3830 cm2), 15° (FWHM) field of view, 30' angular resolution and 6' point source localization ability make it ideally suited for surveying the accreting binary population of the Galaxy at high energy. We present a brief description of the instrument and we also report preliminary imaging results from our recent Southern hemisphere campaign and show the capabilities of this balloon-borne coded aperture telescope for hard X-ray/gamma ray imaging. Several galactic sources have so far been detected above 25 keV with GRIP-2: IE 1740.7-2942, GRS 1758-258, Cyg X-1, GX 339-4, GX 354-0, GX 1+4, GRS 1915+105, Cyg X-3, 4U 1700-377, 4U 1702-429, Terzan 2 and the Crab pulsar.
