This is a brief stab at understanding the balance of gas load and getter capacity. A lot of this may be wrong- that's the point of writing it down for others to read, so please read critically. Also there are...
An x-ray detector based on MCPs. An MCP ALD-coated with tungsten (thermally oxidized after coating) serves as an x-ray photocathode that matches the x-ray stopping depth to the electron escape depth. X-rays hit pore walls at grazing incidence, so that...

Abstract for LIGHT-17 workshop
This document describes MCenter experimental area and how to use G4beamline simulation in order to test LAPPD Time-of-Flight.
This document outlines how the ACC central card firmware interprets signals from the C++ "run-acdc" program. Specifically, it outlines where in the firmware (and how) the functions "Software trigger", "Align LVDS", "CC Read Mode", "Prepare Sync", and "Hardware reset" are...
Report from the summer 2017 REU, working with the PSEC group. Two recipes for the `Margherita Cookbook' are attached.
A report describing the testing of an ANNIE central card based PSEC4 readout system. Includes recipes on how to work with the ACDC and ACC boards.
Recipes for running test cycles to verify that the Margherita 2 is a fully operational LAPPD facility.
Recipes for installing a cesium transport system and internal tile fixturing for the Margherita 2, a large-area picosecond photodetector production facility.
Final report from Benjamin Lunday, summer student 2017.
