摘要

TIGRE跟踪和成像伽玛射线实验的原型正在为2006年秋天的科学气球飞行做准备。TIGRE是一台康普顿望远镜,观测0.5-10兆电子伏特的伽马射线,一对望远镜观测10-100兆电子伏特的伽马射线。它使用多层薄硅条探测器作为康普顿和对转换器和带电粒子跟踪器。事件一致性要求由围绕转换器/跟踪器的CsI(Tl)-光电二极管探测器阵列和下面的大型Na(Tl)-PMT探测器来完成。这次飞行的目的是为了展示TIGRE仪器的背景抑制能力,康普顿反冲电子跟踪和改进的角分辨率对硅作为转换材料。将描述探测器的控制和读出的细节。同样将介绍使用实验室放射性同位素的校准结果。

TIGRE prototype gamma-ray balloon instrument
The prototype TIGRE Tracking and Imaging Gamma-Ray Experiment is being prepared for a scientific balloon flight in fall, 2006. TIGRE is a Compton telescope for 0.5-10 MeV gamma rays and a pair telescope for 10-100 MeV gammas. It uses multiple layers of thin silicon strip detectors as both the Compton and pair converter and the charged particle tracker. The event coincidence requirement is completed with arrays of CsI(Tl)-photodiode detectors surrounding the converter/tracker and large Na(Tl)-PMT detectors below. The purpose of this flight is to demonstrate the background suppression capabilities of the TIGRE instrument with Compton recoil electron tracking and the improved angular resolution for pairs with silicon as the converter material. Details of the control and readout of the detectors will be described. Calibration results using laboratory radioisotopes will likewise be presented.
