Experimental studies of the characteristics of a real-time ion detector—plastic scintillator

利用静电离子加速器对实时离子探测器——塑料闪烁体的特性(包括灵敏度、动态范围、能量响应,及空间分辨等)进行了实验研究,并对闪烁体探测器与其他传统的离子探测器的特性进行了比较.对闪烁体在激光等离子体实验的离子束诊断中的可能应用进行了探讨.塑料闪烁体的应用可满足高重复频率激光等离子体离子加速实验高效率运行的要求,为实验研究提供强有力的支持.

The characteristics of a real-time ion detector--plastic scintillator are experimentally investigated on an electrostatic accelerator. The sensitivity, the dynamic range, the energy response, and the spatial resolution of the plastic scintillator are calibrated, and then compared with those of other ion detectors. Meanwhile, the possibility for the plastic scintillator to be used as a diagnostic tool in laser-driven ion acceleration experiment is discussed. The plastic scintillator provides an efficient tool for online ion detection in the experiments of high-repetition-rate laser-driven ion accelerations.
