detectors to observe the sky in the energy range of 20 keV to 8 MeV with a resolution of ∆E/E ≈ 0.2%. Directional information is obtained using a coded mask. The expected angular resolution is about 2°. The SPI Imaging Test Setup (SPITS) was built at MPE to allow experimental verification of the imaging properties of SPI. SPITS consists of a coded HURA mask and two germanium detectors. The mask is built from 63 opaque tungsten-alloy elements. The two hexagonal Ge-detectors are housed in a common aluminum end cap. They are mounted on an XY-table and can be moved to cover the 19 SPI Ge-detector positions. Mask and Germanium detectors are made of SPI materials, with the exception of some Be parts which have been replaced by thinner Al parts. T...
