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…
Crystal growth and detector performance of large size high-purity Ge crystals
Guojian Wang, Mark Amman, Hao Mei +4
High-purity germanium crystals approximately 12 cm in diameter were grown in a hydrogen atmosphere using the Czochralski method. The dislocation density of the crystals was determi…
The Compton Spectrometer and Imager
John A. Tomsick, Andreas Zoglauer, Clio Sleator +21
In this Astro2020 APC White Paper, we describe a Small Explorer (SMEX) mission concept called the Compton Spectrometer and Imager. COSI is a Compton telescope that covers the bandp…
Maximum Likelihood Compton Polarimetry with the Compton Spectrometer and Imager
Alexander W. Lowell, Steven E. Boggs, Jeng-Lun Chiu +11
Astrophysical polarization measurements in the soft gamma-ray band are becoming more feasible as detectors with high position and energy resolution are deployed. Previous work has…
Optimization of Amorphous Germanium Electrical Contacts and Surface Coatings on High Purity Germanium Radiation Detectors
Mark Amman
Semiconductor detector fabrication technologies developed decades ago are widely employed today to produce gamma-ray detectors from large volume, single crystals of high purity Ge…
Benchmarking COSI's detector effects engine
Clio C. Sleator, Steven E. Boggs, Jeng-Lun Chiu +11
The Compton Spectrometer and Imager (COSI) is a balloon-borne gamma-ray (0.2-5 MeV) telescope with inherent sensitivity to polarization. COSI's main goal is to study astrophysical…
