| 摘 要： | 研制成功一种基于康普顿效应, 用于脉冲裂变n/γ混合场γ强度绝对测量的新型辐射探测器—ICI(绝缘体－导体－绝缘体)探测器. 除具有现有真空康普顿和介质康普顿探测器时间响应快、线性电流大、抗辐射干扰能力强等优点外,该探测器从结构上抑制了真空康普顿在快脉冲γ测量中的前后负冲信号, 并且工作时不需要高真空, 而γ灵敏度却与同尺寸介质康普顿探测器相当. 由于其探测灵敏介质厚度小于2mm, 因而在群脉冲辐射探测中, 不会显著影响后续和周围探测器的
测量环境, 是一种探测脉冲γ射线较理想的探测器.

| Abstract: | A new gamma-ray detecting device called ICI detector has been developed and tested. Like vacuum Compton diode(VCD) and dielectric Compton diode(DCD) generally used in pulsed gamma-ray measurements, ICI detector operates by utilization of the Compton effect and has low sensitivity to gamma-ray fluxes, very fast time response, large linearity and wide dynamic range, it is desired for using the device to measure intense and rapidly changing gamma-ray fluxes. Compared to the existing VCDs and DCDs, the detector requires no vacuum in operation and the active volume is only 2mm thick. |
