This is the file for Square pad anodes. This is the 8mm version, also the latest. The board is not fabricated, because the thickness still needs adjustments for better fabrication with PCBway. Last modified: 02/July/2022 by Jacky L
These are the anode files for stripline anode. This production is 5.2mm, and is currently testing with ACDC at Fermilab. This doc include kicad, gerber and fab instruction. Last modified: 02/July/2022 by Jacky Li
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.
A little note on recent work on the Fermilab Test Beam Time-of-Flight upgrade.
Draft spec for a 1psec 3GHz bandwidth fast-timing ASIC. An Appendix makes the case for wave-form samplilng, in particular for baseline subtraction.
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...
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...
Summer 2019 note about MELZ photo-multiplier tubes.
This little note proposes adding time-sliced information from muon monitors to the stroboscopic neutrino oscillation analysis. Specific proposals include a low intensity run before the halls get too hot to reach muons in the relevant kinematic range, and a description...
ADC data collected on an ACDC card with a generated 100 MHz sine wave input are analyzed with the goal of understanding the measurement noise in the system. Best fits to models are performed, and the residuals of the fits...
Report from the summer 2018 REU, working with the PSEC group
Report from the summer 2018 REU, working with the PSEC group
A report on work done to characterize the self-triggering feature on the PSEC4 ASIC.
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...
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.
Greg Sellberg's "[1032] channel pads w/Ag Epoxy Technique to PC Board Read-out" How to glue Photonis Planacon to the RF-stripline anode card.
Reproduced the result for 0-tile anode in paper "RP strip-line anodes for Psec large-area MCP-based photodetectors". Elaborated on several issues regarding the setup.
Revision 0 of the Margherita User's Manual. This document was written as a draft, to be revised as we learn more and more about how to operate and fabricate a tile with the Margherita dual vacuum chamber fabrication system.
This is a paper written for the 335 experimental physics project first year graduate course. Beyond an overview of the supermodule, it provides a more detailed description of the pairing and second localization techniques.
A draft document describing some issues with respect to the interactions of the High Level DAQ (ie on DAQ PC) and the DAQ device Firmware. Specific application to 160 channel PSEC3/4 center card FPGA configuration. Dec 2, 2011 Ed May
