Abstract

The precise reconstruction of Compton-scatter events is paramount for an imaging medium-energy gamma-ray telescope. The proposed AMEGO-X is enabled by a silicon tracker utilizing AstroPix chips - a pixelated silicon HVCMOS sensor novel for space use. To achieve science goals, each 500 × 500 µm² pixel must be sensitive for energy deposits ranging from 25-700 keV with an energy resolution of 5 keV at 122 keV (< 10%). This is achieved through depletion of the 500 µm thick sensor, although complete depletion poses an engineering and design challenge. This talk will summarize the current status of depletion measurements highlighting direct measurement with TCT laser scanning and the agreement with simulation. Future plans for further testing will also be identified.
