新型多像素硅光子探测器及其在T2K中的应用

Novel Multi-pixel Silicon Photon Detectors and Applications in T2K

Dmitriy Beznosko

摘要:

如今,诸如高能物理(HEP)、医学成像设备、便携式辐射探测器等的众多领域,需要一种坚固、小型、可靠和容易获得的光子检测器,其在各种环境中,例如在强磁场存在下是稳定的。最近可用的$\sim$ 1 mm $^{\textrm{2}}$有源区多像素光子计数器(MPPC)传感器,由滨松光子学公司生产,已被发现是可靠的,是一个有吸引力的选择,用于HEP应用。以下传感器特性已经过T2 K合作组织的全面测试:增益、暗噪声、检测效率、可靠性。这些似乎是稳定的;此外,还评估了许多器械之间的特征扩散。具有较大面积的传感器正在开发用于成像和直接与闪烁体耦合的目的。

英文摘要:

Nowadays, numerous fields such as High Energy Physics (HEP), medical imaging devices, portable radiation detectors etc., require a robust, miniature, reliable and readily available photon detector that is stable in a variety of environments, such as the presence of strong magnetic fields. The recently available $\sim$1mm$^{\textrm{2}}$ active area Multi-pixel Photon Counter (MPPC) sensors, produced by Hamamatsu Photonics, have been found to be reliable and an attractive choice for the HEP applications. The following sensor characteristics have been thoroughly tested by T2K collaboration: gain, dark noise, detection efficiency, reliability. These appear to be stable; in addition, the characteristic spread between numerous devices was assessed. Sensors with larger area are being developed for imaging and direct-to-scintillator coupling purposes.
