Micro-channel-plate-based photo-detectors are unique in being capable of covering areas of many square-meters while providing sub-millimeter space resolution, time resolutions of less than 10 picoseconds for charged particles, time resolutions of 30-50 psec for single photons. Incorporating a capacitively-coupled anode...
We have designed and prototyped the process steps for the batch production of large-area micro-channel-plate photomultipliers (MCP-PMT) using the ``air-transfer'' assembly process developed with single $\LAPPDTM$ modules. Results are presented addressing the challenges of designing a robust package that can...
Heated metal filaments under electric fields and low pressures of alkali metal gas eject electrons by thermionic emission as a function of the pressure of the gas and the temperature of the filament. To explore this process in a program...

We report on performance results achieved for recently produced LAPPDs. 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...

If the resistive divider is internal, most of the photocurrent does not make it out of the PMT.
Version of the capacitive coupling paper as published in NIMA
First submission to NIMA of the Capacitive Coupling paper. Discusses the capacitive anode/pickup configuration of the Gen-II ceramic tile, which uses the "Inside-Out" scheme.

This is Evan Angelico's 335 final report, as it was when it was turned in late at night on May 25th 2016. It will likely be revised into a different format, but this is VERSION 1.
There is very little experimental information on the St707 getter planned for use in the tile. This paper attempts to characterize the pumping speed of the getter at various activation environments. We also take a look at how this pumping...
