| 摘 要： | 以开展能量响应平坦的真空康普顿探测器为目的，采用厚薄材料叠加补偿设计思想，使用蒙特卡罗方法，对真空康普顿探测器的灵敏度能量响应进行了优化设计。优化的探测器系统采用0.01,1.00 mm厚Au叠加的发射极，3 mm厚Fe前窗以及3 mm挡铅。在f40 mm准直下，实现了在0.4~7.0 MeV 能区内，探测器本征灵敏度极值变化小于10.7%。该能量响应平坦性优于当前各种常见的探测器。

| Abstract: | The work focuses on the study of vacuum Compton detector(VCD) with flat energy response. The proposed VCD adopts a compensation design of the emitter, i.e. a superimposition of materials of varied thicknesses, and is optimized with Monte Carlo method. The optimally designed VCD consists of an emitter with the superimposition of 0.01, 1 mm-thick Au, a 3 mm-thick Fe front window and a 3 mm-thick Pb shielding. Its non-flatness of energy response to gamma-ray is less than 10.7% over 0.4-7.0 MeV energy zone. The flatness of energy response to gamma ray of this VCD is more excellent than current gamma detectors’. |
