“…AMEGO consists of four subsystems that work together to operate as a Compton and pair Figure 5.2: The AMEGO Tracker is designed around layers of DSSDs which measure the energy deposited from Compton scattering events and pair conversion interactions and is sensitive in the energy range ∼100 keV to >1 GeV. Prototype development of the Tracker is currently underway [404,492].…”

Naturally occurring particle accelerators shine brightly throughout the universe, inviting us to discover fundamental laws and hone our theories if we look in their directions with the right detectors. Gamma-rays, the most energetic photons, carry information from the far reaches of extragalactic space with minimal interaction or loss of information. They bring messages about particle acceleration in environments so extreme they cannot be reproduced on earth for a closer look. Gamma-ray astrophysics is so complementary with collider work that particle physicists and astroparticle physicists are often one in the same.Gamma-ray instruments, especially the Fermi Gamma-ray Space Telescope, have been pivotal in major multi-messenger discoveries over the past decade. There is presently a great deal of interest and scientific expertise available to push forward new technologies, to plan and build space-and ground-based gamma-ray facilities, and to build multimessenger networks with gamma rays at their core. It is therefore concerning that before the community comes together for planning exercises again, much of that infrastructure could be lost to a lack of long-term planning for support of gamma-ray astrophysics. Gamma-rays with energies from the MeV to the EeV band are therefore central to multiwavelength and multi-messenger studies to everything from astroparticle physics with compact objects, to dark matter studies with diffuse large scale structure.These science goals and the excitement of new discoveries have generated a wave of new gamma-ray facility proposals and programs. Since the legacy of existing facilities is well covered in many other places, this paper highlights new and proposed gamma-ray technologies and facilities that have each been designed to address specific needs in the measurement of extreme astrophysical sources that probe some of the most pressing questions in fundamental physics for the next decade. The proposed instrumentation would also address the priorities laid out in the recent Decadal Survey of Astronomy and Astrophysics (Astro2020), a complementary study by the astrophysics community that provides opportunities also relevant to Snowmass.

“…Each layer contains four 4×4 arrays of DSSDs, totaling 3840 silicon wafers each measuring 9.5 cm square. To mature this technology, the AMEGO team is building a prototype of the four subsystems and are working towards a balloon flight to test the instrument in 2023 [404,492]; see Figure 5.2.…”

“…After the end of INTEGRAL mission, the future of observations in sub-MeV and MeV regime is unclear. Indeed, future proposals for large-scale missions are being considered -ASTROGAM [4] in Europe, COMPAIR [5] and AMEGO [6] in the US but, given the typical development time, those will be ready for use (if approved) in 2030s at earliest. Possible solution to bridge the time gap between the present and future missions could come from the development of light telescopes that can be launched on state-of-the art nanosatellites.…”

Study of a small scale position-sensitive scintillator detector for γ-ray spectroscopy

Precision measurement of the energy and direction of gamma-rays plays a key role in many fields such as medical imaging, nuclear spectroscopy, and astrophysics. In astrophysics position sensitive gamma-ray detectors are used to study diffuse and point-like sources. These space-born gamma-ray telescopes, however, are mainly based on large arrays of detectors which are expensive, complex, and take long time to build. A different approach is the use of detector with similar energy and angular resolution, but small enough to be deployed on nanosatellites.We research a design based on monolithic scintillator and multi-pixel photo-sensor. At first we are focused on characterization of CeBr 3 scintillator detectors. Bench test experiments were performed with CeBr 3 crystal with square surfaces and thicknesses of 10 mm and 25 mm. The crystals were coupled to a single-anode PMT and the outcome compared to Geant4 simulation.
