Abstract
This paper describes the balloon-borne coded-aperture telescope, GRIP-2, which is designed for imaging observations of astrophysical sources in the 30 keV-2 MeV band. GRIP-2 employs the rotating hexagonal coded-mask imaging technique pioneered by the Caltech GRIP-1 [Cook et al., IEEE Trans. Nucl. Sci. NS-31 (1984) 771] instrument. GRIP-2 has an angular resolution of 33′ over a 15° FWHM field of view. A large (3850 cm2 geometric area) NaI(Tl)CsI(Na) phoswich detector provides excellent source detection sensitivity. We describe here the instrument design, performance, and preliminary results from the first two balloon flights.
