Abstract
We report simulation and resolution evaluation of monolithic position sensitive detectors with different surfaces. The best result was obtained using a combination of rough polishing of the crystal surface and a Teflon wrapper with a resolution in the interaction depth of dZ = 0.89 ± 0.01 mm. The best planar resolution dX = 0.53 ± 0.01 mm is obtained for a finely polished plate with an ESR film. The diffuse reflector also demonstrates an increase in light collection by 33% compared to the specular one.
