摘要:

我们报告最近生产的LAPPD-最大的商用平面几何形状的微通道板的基础上实现的性能结果。这些结果包括高达$10^{7}$的电子增益,低暗噪声率($\sim$ 100 Hz/cm $^{2}$,增益为$6\cdot10^6$),单个光电子(PE)定时分辨率为$\sim$ 50皮秒RMS(电子有限公司),单光电子空间分辨率为3.2mm(电子有限公司)和0.8mm RMS的光电阴极和高QE(在某些单位中约25%或更高)均匀双碱光电阴极。LAPPD是中微子实验(如ANNIE、WATCHMAN、DUNE)、粒子对撞机实验(如EIC)、无中微子双β衰变实验(如THEIA)、医学和核不扩散应用中的良好候选者。

英文摘要:

We report on performance results achieved for recently produced LAPPDs - largest comercially available planar geometry photodetectors based on microchannel plates. These results include electron gains of up to $10^{7}$, low dark noise rates ($\sim$100 Hz/cm$^{2}$ at a gain of $6\cdot10^6$), single photoelectron (PE) timing resolution of $\sim$50 picoseconds RMS (electronics limited), and single photoelectron spatial resolution along and across strips of 3.2mm (electronics limited) and 0.8 mm RMS respectively and high (about 25\% or higher in some units) QE uniform bi-alkali photocathodes. LAPPDs is a good candidate to be employed in neutrino experiments (e.g. ANNIE, WATCHMAN, DUNE), particle collider experiments (e.g. EIC), neutrinoless double-beta decay experiments (e.g. THEIA), medical and nuclear non-proliferation applications.
