Abstract

COCOA (COmpact COmpton cAmera) is a next-generation gamma-ray telescope designed for astrophysical observations in the MeV energy range. The detector comprises a scatterer volume employing the LiquidO detection technology and an array of scintillating crystals acting as absorber. Surrounding plastic scintillator panels serve as a veto system for charged particles. The detector’s compact, scalable design enables flexible deployment on microsatellites or high-altitude balloons. Gamma rays at MeV energies have not been well explored historically (the so-called “MeV gap”) and COCOA has the potential to improve the sensitivity in this energy band.

用于mev尺度伽玛射线天体物理观测的紧凑型康普顿照相机

COCOA （COmpact COmpton cAmera）是下一代伽玛射线望远镜，专为MeV能量范围内的天体物理观测而设计。探测器包括采用LiquidO探测技术的散射体和作为吸收体的闪烁晶体阵列。周围的塑料闪烁板作为带电粒子的否决系统。该探测器紧凑、可扩展的设计使其能够灵活地部署在微型卫星或高空气球上。历史上，MeV能量的伽马射线还没有被很好地探索过（所谓的“MeV间隙”），而COCOA有可能提高这一能量带的灵敏度。
