Atmospheric Response for MeV Gamma Rays Observed with Balloon-Borne Detectors
Chris Karwin, Carolyn Kierans, Albert Shih +9
The atmospheric response for MeV gamma rays (~ 0.1 - 10 MeV) can be characterized in terms of two observed components. The first component is due to photons that reach the detector…
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…
Large-area Si(Li) detectors for X-ray spectrometry and particle tracking in the GAPS experiment
Field Rogers, Mengjiao Xiao, Kerstin M. Perez +14
The first lithium-drifted silicon (Si(Li)) detectors to satisfy the unique geometric, performance, and cost requirements of the General Antiparticle Spectrometer (GAPS) experiment…
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…
The Design and Performance Characteristics of the NRL4 ASIC Developed for the COSI Small Explorer Gamma-ray Satellite
Jarred M. Roberts, Clio Sleator, Eric Wulf +5
Next-generation gamma-ray observatories aim to enable precision measurements in high-energy astrophysics using advanced semiconductor detector technologies. Meeting the scientific…
Imaging the 511 keV positron annihilation sky with COSI
Thomas Siegert, Steven E. Boggs, John A. Tomsick +10
The balloon-borne Compton Spectrometer and Imager (COSI) had a successful 46-day flight in 2016. The instrument is sensitive to photons in the energy range - MeV. Compton t…
Imaging and Spectral Fitting of Bright Gamma-ray Sources with the COSI Balloon Payload
Jarred M. Roberts, Steven Boggs, Thomas Siegert +17
The Compton Spectrometer and Imager balloon payload (COSI-Balloon) is a wide-field-of-view Compton -ray telescope that operates in the 0.2 - 5 MeV bandpass. COSI-Balloon had a…
The 2016 Super Pressure Balloon flight of the Compton Spectrometer and Imager
Carolyn A. Kierans, Steven E. Boggs, Jeng-Lun Chiu +11
The Compton Spectrometer and Imager (COSI) is a balloon-borne, soft-gamma ray imager, spectrometer, and polarimeter with sensitivity from 0.2 to 5 MeV. Utilizing a compact Compton…
Large-area Si(Li) Detectors for X-ray Spectrometry and Particle Tracking for the GAPS Experiment
Field Rogers, Mengjiao Xiao, Kerstin Perez +15
Large-area lithium-drifted silicon (Si(Li)) detectors, operable 150°C above liquid nitrogen temperature, have been developed for the General Antiparticle Spectrometer (GAPS) ballo…
