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...
We describe the design and underlying principles of a tungsten-filament gauge for the partial vapor pressure of cesium. Operation is based on the temperature depen- dence of electronic thermionic emission from a tungsten filament with a thermally equi- librated partial...

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...
Poster presentation at the 14th Pisa Meeting on Advanced Detectors, May 2018
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.
ICHEP 2016 presentation on the In-Situ LAPPD
Todd Seiss's final 335 report, as submitted on May 25th 2016. It is likely to be updated in the future.

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...
