Development of Astronomical Observations in the MeV Gamma-ray Band Using a Balloon-borne Gamma-ray Camera with a Wide Field of View

我们已经开发了一台康普顿伽马射线相机，它具有宽视场和高灵敏度，用于开发MeV伽马射线波段，在X射线到伽马射线波段中，天文观测落后于大多数。该相机基于一种新的方法，可以探测在探测器中康普顿反冲的电子的三维轨迹，其中伽马射线是康普顿散射的。该相机由一个使用气体室的三维跟踪器和一个带有像素化闪烁体的伽马射线相机组成。此外，我们还开发了一种用于气球飞行的紧凑、低功耗的读出系统

We have developed a Compton gamma-ray camera with a wide field of view and high sensitivity to develop the MeV gamma-ray band where astronomical observations lag behind the most in the X-ray to gamma-ray band. The camera is based on a new method of detecting the three dimensional track of an electron Compton-recoiled in a detector where a gamma-ray is Compton-scattered. The camera consists of a three dimensional tracker using a gas chamber and a gamma-ray camera with a pixelatedscintillator. In addition, we have developed a compact readout system with low power consumption for a balloon flight
