Development of versatile gamma-ray detectors with good timing resolution making use of Cherenkov photons

使用探测器中产生的散射光子进行了伽马射线测量。然而，一般来说，具有良好能量分辨率的检测器具有较差的定时分辨率。在这项研究中，我们成功地开发了探测机制，通过测量伽马射线的能量和时间，分别使用闪烁光子和切伦科夫光子。因此，我们可以将这种方法应用于粒子物理学中使用的电磁量热计和最近高度先进的PET医学检查。探测器在这两个领域的性能都得到了更大的改善。

A gamma-ray measurement has been performed using scintillating photons generated in a detector. However, in general, detectors with good energy resolution have poor timing resolution. In this research, we successfully developed the detection mechanism by measuring gamma-ray energy and timing using scintillating photons and Cherenkov photons, respectively. As a result, we can apply this method to electro-magnetic calorimeters used in particle physics and recently highly advance PET medical examination. The detector performance in both fields is higher improved.
