We developed the small phoswich type detector for the measurements of the radiation quality in the heavy ion radiothrapy. The detection part of this detecor consists of the hollow type CaF2 crystal and liquid organic scintillator. And we lead out the scintillation using the optical fiber. This study has shown that this type detector is possible to identify charged particles and secondary gamma rays by the result of the experiment using accelerator. And it has shown that higher energy resolution of this detector is required for the measurement of the precise radiation quality.

我们开发了小的富裕型检测器，用于测量重离子放射治疗中的辐射质量。该检测的检测部分由空心型CAF2晶体和液体有机闪烁体组成。我们使用光纤领导闪烁。这项研究表明，通过使用加速器的实验结果，这种类型的检测器可以识别带电的颗粒和继发性伽马射线。它表明，测量精确的辐射质量需要该检测器的较高能量分辨率。
