Abstract

Pixelated High Rate Picosecond Photon Detectors (HRPPDs) by Incom Inc. are promising photosensors for use in Ring Imaging CHerenkov (RICH) detectors, where a high gain, sub-mm position resolution and sub-100ps timing resolution are required in a single photon mode. Quantum Efficiency (QE) has been measured for the first batch of EIC HRPPDs both by Incom and EIC research groups at Jefferson Lab and Brookhaven Lab, with peak values at

\sim

365 nm typically exceeding 30%. In this study, we present a first direct measurement of Photon Detection Efficiency being equal to (17.1 ± 0.1 [stat]

\pm

0.3 [sys])% at 398.6 nm, for a pixel near the center of HRPPD, in a photoelectron pulse counting mode using a picosecond diode laser. HRPPD QE at the same spot and at the same wavelength was evaluated to be (24.4 ± 0.1 [stat]

\pm

0.3 [sys])%, leading to a Collection Efficiency estimate of (70.3 ± 1.6)%, which is consistent with the expectations.

HRPPD绝对单光子探测效率的评价

Incom公司的像素化高速率皮秒光子探测器（HRPPDs）是一种很有前途的光传感器，用于环成像切伦科夫（RICH）探测器，在单光子模式下需要高增益、亚毫米位置分辨率和亚100ps定时分辨率。Incom和杰斐逊实验室和布鲁克海文实验室的EIC研究小组已经测量了第一批EIC hrppd的量子效率（QE），在~ 365 nm处的峰值通常超过30%。在这项研究中，我们提出了第一个直接测量光子探测效率等于（17.1±0.1 [stat]±0.3 [sys]）%，在398.6 nm，在一个像素附近的HRPPD中心，在光电子脉冲计数模式使用皮秒二极管激光器。同一点、同一波长的HRPPD QE值为（24.4±0.1 [stat]±0.3 [sys]）%，收集效率为（70.3±1.6）%，与预期一致。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
