Anode Pad Sharing NIM Paper as Published. Abstract: Micro-channel-plate-based photo-detectors are unique in being capable of covering very large areas such as those required in elementary particle and nuclear physics, while providing sub-millimeter space resolution, time resolutions of less than...
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.
Draft Testbeam Proposal
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...
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 at TIPP, Amsterdam; June 2014
Poster presentation at the 14th Pisa Meeting on Advanced Detectors, May 2018
Invited Talk at the 5th International Conference on Micro-Pattern Gas Detectors (MPGD2017); 22-26 May, 2017; Temple University, Philadelphia
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...
Version of the capacitive coupling paper as published in NIMA
Spherical harmonics paper as submitted to NIM.
We report pilot production and advanced development performance results achieved for Large Area Picosecond Photodetectors (LAPPD TM).
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.

Optical TPC paper as published in NIM
Novel large area microchannel plates (MCPs) constructed using micro-capillary arrays functionalized by atomic layer deposition (ALD) have been successfully demonstrated in large for- mat detectors (10 cm and 20 cm) with cross delay line and cross strip readouts. Borosilicate micro-...
The development of large area, high performance, photon counting, imaging, timing detectors based on novel microchannel plate technology potentially offers significant advantages in a number of applications. To explore this, large area (20 cm) microchannel plates have been constructed using...
Microchannel plates that have been constructed by atomic layer deposition of resistive and secondary emissive layers, onto borosilicate glass microcapillary arrays provide a novel alternative to conventional microchannel plates for detection of radiation and particles. Conventional microchannel plates can also...
Novel microchannel plates have been constructed using borosilicate glass micro-capillary array substrates with 20 mm and 10 mm pores and coated with resistive, and secondary electron emissive, layers by atomic layer deposition. Microchannel plates in 33 mm, 50 mm and...
