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...

Andrey's farewell talk: "Wine and Cheese" seminar at Fermilab. August 21, 2020.
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...
White Paper on use of large-area MCPs assembled without the usual bialkali cathodes as the active elements in sampling calorimeters.
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...
Talk at TIPP, Amsterdam; June 2014
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...
