Abstract

This paper describes a balloon-borne coded-aperture y-ray telescope for galactic and extragalactic astronomy observations. The instrument, called GRIP (Gamma Ray Imaging Payload), is designed for measurements in the energy range from 30 keV to 5 MeV with an angular resolution of 0.6° over a 20° field of view. Distinguishing characteristics of the telescope are a rotating hexagonal coded-aperture mask and a thick NaI scintillation camera. Rotating hexagonal coded-apertures and the development of thick scintillation cameras are discussed in Cook et al. [1984 and 1985, referred to as Papers I and II respectively].
