Title: A gamma-ray telescope with arc minute resolution
Abstract: A prototype imaging telescope of a kind that could be used in a future γ-ray astronomy mission has been tested using a quasi-point source of 20 MeV γ radiation. The results have demonstrated the ability to reconstruct images of the source at various positions within the field of view of the telescope. The point-spread function of the telescope was improved by nearly two orders of magnitude over that of a track chamber alone through the use of a coded aperture mask. This work has demonstrated for the first time the possibility of achieving arc minute source location with future γ-ray space telescopes. This would enable point-like γ-ray sources to be located with that precision while extended objects could be mapped with a resolution of about 10 arc min.
