Abstract
We describe simulations of a Compton telescope
gamma-ray detector. The model is based on scintillation detectors
and low-mass, photosensitive micro-pattern detectors, particu-
larly the plasma panel sensor. The detector model has
ten to twenty layers, to maximize the probability of Compton
scattering while minimizing multiple scattering in a single layer.
The simulations explore optimizing the micro-pattern detec-
tor pixel geometry, the scintillator material, the total detector
thickness, and the number of layers. In addition, we explored
algorithms for determining the interaction position, total energy
and discriminating Compton scattering from other processes.
Our initial results indicate that this kind of Compton telescope
can be much more efficient that silicon or germanium-based
telescopes while providing very good position resolution.
