Abstract

A new design for a broad-band imaging telescope intended for operation within the energy range from about 15 keV to more than 1 MeV is described. The detection plane of this coded aperture telescope consists of an array of position-sensitive scintillation counters that are designed to provide a constant spatial resolution of 1 cm over the full energy range. The detection elements are intimately shielded by the combination of a phoswich veto system and an active shield. The predicted background rates indicate that the telescope could provide a good imaging capability and a competitive sensitivity within a modest payload mass.
