This board is designed to allow access to the typical 30 signal channels from a SAMTEC connectorized anode or ACDC board using 5 SMA input/outputs and self-terminating RF selector chips. The files contained include KiCad design files, gerbers for fabrication,...
Those are the Project files for Anodes(Square, Sin, and Stripline), with Kicad files for PCB Design, Fabrication instructions, Gerber files, and a Jpeg for quick reference. The current version is on Jan 11, 2021, and sent for fabrication.
Draft spec for a 1psec 3GHz bandwidth fast-timing ASIC. An Appendix makes the case for wave-form samplilng, in particular for baseline subtraction.
Stroboscopic Beam Timing paper as published in PHYSICAL REVIEW D 100, 032008 (2019) We propose to use a higher-frequency rf bunch structure for the primary proton beam on target and precision timing to select different energy and flavor spectra from...
The batch-production air-transfer paper as published: Review of Scientific Instruments 91, no. 5 (2020): 053105; 28 April 2020
Gerber files are under pad-pickup-64-gerber folder. There are 64 minus 4 square pads on the front layer, four corner pads excluded. This is because only 60 channels are available. Each pads are labeled from 1 to 64, horizontal then vertical...
Anode Pad Sharing NIM Paper as Published: Nuclear Inst. and Methods in Physics Research, A 985 (2021) 164702; 22 Sept, 2020 \\~~~~~~~~~~~~~ Abstract: Micro-channel-plate-based photo-detectors are unique in being capable of covering very large areas such as those required in...
A system of Large Area Picosecond Photodetectors (LAPPDTM) has been constructed at the Fermilab Test Beam Facility (FTBF) to measure charged particles in a time-of-flight configuration. Cherenkov photons produced by charged particles passing through the glass window induce signals that...
The properties of radiation emitted when a single electron passes through an undulator element, though quantum in nature due to small occupation number, should extrapolate to the same observed properties of undulator radiation in the high occupation number of an...
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 photo- multipliers (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...

We propose a relatively simple method to measure the event time in liquid Argon (LAr) neutrino detectors that takes advantage of the topological reconstruction of each event {\it prior} to a one-parameter' fit for the time using Precision-4D' photodetectors. A...
Draft Testbeam Proposal
We report on performance results achieved for recently produced LAPPDs. LAPPDs is a good candidate to be employed in neutrino experiments (e.g. ANNIE [1], WATCHMAN [2], DUNE [3]), particle collider experiments (e.g. EIC [4]), neutrinoless double-beta decay experiments (e.g. THEIA...

Talk given at LIGHT17 about OTPC development and simulations for a second generation OTPC
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
Evan Angelico's ICHEP2016 poster on the capacitively coupled readout testing.
Todd Seiss's final 335 report, as submitted on May 25th 2016. It is likely to be updated in the future.
Slides from a presentation on top seal at SORMA 2016
Todd Seiss's 335 poster, presented on June 1 2016. Topic is Inside-Out LAPPD and pad pattern readout boards for use at the LHC.
Evan's 335 poster, presented at the 335 session on June 1 2016. Topic is Inside-Out LAPPD
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...
