Silicon sensors with high time resolution can help particle identification in the International Linear Collider (ILC). We are studying Low Gain Avalanche Diodes (LGADs) as a high timing resolution sensor. As a step to develop LGADs, we are now focusing to characterize Avalanche Photo Diode (APD)s, because the APDs has the same multiplication structure as LGADs. We studied the characteristics of APDs with particles from radioisotopes.

用于精确计时测量的硅传感器的研究

具有高时间分辨率的硅传感器可以帮助国际直线对撞机 (ILC) 中的粒子识别。我们正在研究作为高时序分辨率传感器的低增益雪崩二极管 (LGAD)。作为开发 LGAD 的一步，我们现在专注于表征雪崩光电二极管 (APD)，因为 APD 具有与 LGAD 相同的乘法结构。我们用来自放射性同位素的粒子研究了 APD 的特性。
