摘要:

VSiPMT(真空硅光电倍增器管)是我们为革命性光子探测器提出的创新设计。其主要思想是用SiPM(G-APD)代替PMT的经典倍增极链,后者充当电子检测器和放大器。其目的是使光电阴极的大灵敏区域与SiPM技术的性能相匹配。VSiPMT具有许多吸引人的功能。特别地,低功耗和优异的光子计数能力。为了证明这一想法的可行性,我们首先测试了一种特殊的非窗口SiPM(MPPC)的电子探测器和电流放大器的性能。由于这一结果,滨松实现了两个VSiPMT工业原型。在这项工作中,我们提出了一个完整的VSiPMT原型表征的结果。

英文摘要:

The VSiPMT (Vacuum Silicon PhotoMultiplier Tube) is an innovative design we proposed for a revolutionary photon detector. The main idea is to replace the classical dynode chain of a PMT with a SiPM (G-APD), the latter acting as an electron detector and amplifier. The aim is to match the large sensitive area of a photocathode with the performance of the SiPM technology. The VSiPMT has many attractive features. In particular, a low power consumption and an excellent photon counting capability. To prove the feasibility of the idea we first tested the performance of a special non-windowed SiPM by Hamamatsu (MPPC) as electron detector and current amplifier. Thanks to this result Hamamatsu realized two VSiPMT industrial prototypes. In this work, we present the results of a full characterization of the VSiPMT prototype.
