Description

We report on the initial development and testing of a Compton telescope that is composed of scintillating fibers and position sensitive photomultipliers. Initial tests of the telescope result in a 17.5 mrad (rms) angular resolution for 1.2 MeV photons from a collimated 60Co gamma source. This type of device can be used for constructing large area telescopes for gamma ray astronomy. The results from the prototype arrangement suggest that angular resolutions better than 4 mrad (rms) at 1.2 MeV and 1 mrad (rms) at 5 MeV may be obtainable by reducing all possible systematic errors.
