AbstractAbstract
[en] A coded aperture imaging system has been designed for the Gamma-Ray Imaging Spectrometer (GRIS). The system is optimized for imaging 511-keV positron-annihilation photons. For a galactic center 511-keV source strength of 10-3 cm-2s-1, the source location accuracy is expected to be +-0.20
