The cosipy library: COSI's high-level analysis software
Israel Martinez-Castellanos, Savitri Gallego, Chien-You Huang +72
The Compton Spectrometer and Imager (COSI) is a selected Small Explorer (SMEX) mission launching in 2027. It consists of a large field-of-view Compton telescope that will probe wit…
Characterizing and correcting electron and hole trapping in germanium cross-strip detectors
Sean N. Pike, Steven E. Boggs, Jacqueline Beechert +4
We present measurements of electron and hole trapping in three COSI germanium cross-strip detectors. By characterizing the relative charge collection efficiency (CCE) as a function…
Analytical Fitting of Gamma-ray Photopeaks in Germanium Cross Strip Detectors
Steven E. Boggs, Sean N. Pike
In an ideal germanium detector, fully-absorbed monoenergetic gamma-rays will appear in the measured spectrum as a narrow peak, broadened into a Gaussian of width determined only by…
Modeling Charge Cloud Dynamics in Cross Strip Semiconductor Detectors
Steven E. Boggs
When a -ray interacts in a semiconductor detector, the resulting electron-hole charge clouds drift towards their respective electrodes for signal collection. These charge clouds…
Calibrations of the Compton Spectrometer and Imager
Jacqueline Beechert, Hadar Lazar, Steven E. Boggs +12
The Compton Spectrometer and Imager (COSI) is a balloon-borne soft -ray telescope (0.2-5 MeV) designed to study astrophysical sources. COSI employs a compact Compton telescope d…
Measurement of Galactic Al with the Compton Spectrometer and Imager
Jacqueline Beechert, Thomas Siegert, John A. Tomsick +11
The Compton Spectrometer and Imager (COSI) is a balloon-borne compact Compton telescope designed to survey the 0.2-5 MeV sky. COSI's energy resolution of 0.2% at 1.8 MeV, sin…
