论文摘要
我们介绍了在大面积Picsecond光电探测器（LAPPD）中取得的进步，这是一个8“ $ \ times $ 8”的微通道板板光电层管（MCP-PMT），因为2018年在Incom，Incom启动了Pilot生产。Gen-I LAPPD利用了直接充电量读取了Gen-i Lappd。新型的Gen-II LAPPD采用了内部电阻薄膜，可将其与可自定义的外部信号读数板相连，从而简化了生产。 Gen-II Lappd的活跃面积为373 cm $^2 $，能够具有高单个光电子（PE）$ \ sim $ 10 $ 10 $^7 $的增益（$ \ sim $ \ sim $ 1 khz/cm $^2 $），单个PE的单个pe时定时分辨率$ \ sim $ \ sim $ 65 ps，$ 65 ps，＆$ \ \ \ \ \ \ m nationcal coslution（o）$} $} $} res（mm）ressortion {o} res（mm）{o}。加上紫外线融合二氧化硅窗口，LAPPD具有高量子效率（QE）bialkali光电极$> $> $ 30％，光谱响应降至$ \ sim $ 165 nm。 LAPPD是电磁热量计（ECAL）时层，基于光子的中微子探测器，高能量对撞机实验，医学成像系统和核非散射应用的绝佳候选者。
We present advances made in the Large Area Picosecond Photodetector (LAPPD), an 8" $\times$ 8" microchannel plate photomultiplier tube (MCP-PMT), since pilot production was initiated at Incom, Inc. in 2018. The Gen-I LAPPD utilizes a stripline anode for direct charge readout. The novel Gen-II LAPPD employs an internal resistive thin-film which capacitively couples to a customizable external signal readout board, streamlining production. The Gen-II LAPPD, with an active area of 373 cm$^2$, is capable of high single photoelectron (PE) gain of $\sim$10$^7$, low dark rates ($\sim$1 kHz/cm$^2$), single PE timing resolution of $\sim$65 ps, and $\mathcal{O}$(mm) position resolution. Coupled with a UV-grade fused silica window, the LAPPD features a high quantum efficiency (QE) bialkali photocathode of $>$30% with spectral response down to $\sim$165 nm. The LAPPD is an excellent candidate for electromagnetic calorimeter (ECAL) timing layers, photon-based neutrino detectors, high energy collider experiments, medical imaging systems, and nuclear non-proliferation applications.
