Web17 feb. 2024 · The emission of very-high-energy (VHE) photons (E > 100 GeV) in blazars is closely connected to the production of ultra-relativistic particles and the role of these γ-ray sources as cosmic particle accelerators. This work focuses on a selection of 22 γ-ray objects from the 2BIGB catalogue of high-synchrotron-peaked sources, which are … Webcapturing only part of the original gamma-ray energy. Some of the remaining or lost energy actually leaves the detector. If we could capture these lost energy parts, we could reject the part of the gamma-ray energy captured in the HPGe. In a Compton Suppression System (CSS), (Fig. 6) the HPGe detector is surrounded by a NaI(Tl) annular detector ... cumulative capacity battery
