Next-generation gamma-ray observatories aim to enable precision measurements in high-energy astrophysics using advanced semiconductor detector technologies. Meeting the scientific…
Characterizing, correcting, and repairing the effects of radiation damage in the COSI germanium cross-strip detectors
Steven E. Boggs, Sophia E. Haight, Sean N. Pike +5
The Compton Spectrometer and Imager (COSI) is a gamma-ray survey telescope utilizing a compact Compton imager design, enabled by an array of 16 high-resolution germanium cross-stri…
Proton Radiation Damage and Annealing of COSI p-type Cross-strip HPGe Detectors
Sophia E. Haight, Steven E. Boggs, Gabriel Brewster +7
In order to understand the effects of a space radiation environment on cross-strip germanium detectors, we investigated the effects of high-energy proton damage on a COSI detector…
Enhancing Compton telescope imaging with maximum a posteriori estimation: a modified Richardson-Lucy algorithm for the Compton Spectrometer and Imager
Hiroki Yoneda, Thomas Siegert, Israel Martinez-Castellanos +23
We present a modified Richardson-Lucy (RL) algorithm tailored for image reconstruction in MeV gamma-ray observations, focusing on its application to the upcoming Compton Spectromet…
Characterizing hole trap production due to proton irradiation in germanium cross-strip detectors
Sean N. Pike, Steven E. Boggs, Gabriel Brewster +6
We present an investigation into the effects of high-energy proton damage on charge trapping in germanium cross-strip detectors, with the goal of accomplishing three important meas…
