摘要: 介绍了ZnO:Ga晶体对重复频率快脉冲硬X 射线的时间响应，利用X射线荧光分析仪测量了ZnO:Ga晶体对10～100 keV硬X射线的能量响应。结果表明:ZnO:Ga晶体对硬X射线响应的上升时间为316 ps,半高宽为440 ps;对40 keV以上的X射线的能量响应很平坦。该晶体可以作为一种新颖的硬X射线探测元件。Abstract: This paper introduces the time response of a new type ZnO:Ga crystal to a fast rep-rate pulse hard X-ray. The hard X-ray energy spectrum (from 10 keV to 100 keV ) was measured by X-ray fluorescence analysis apparatus. The results show that the rise time is 316 ps, the FWHM is 440 ps, and the energy response to hard X-ray is flat when the X-ray energy greater than 40 keV. The ZnO:Ga crystal could be used as a component for hard X-ray detection.
