Development of Gen-II LAPPDTM Systems For Nuclear Physics Experiments
- Incom Inc.,Charlton, MA (United States); Incom Inc.
The technical objectives of this Phase I program were to; Demonstrate proof of concept of a pin-free pixelated readout using an inside-out approach. “Inside-out” is a novel approach for having the ground plane on the inside (floor of the anode facing the MCP stack-up) and anode pads on the outside of the LAPPD. The goal is a demonstration of capacitive coupling through the bottom anode plate (9.02 x 8.66”), using ceramic, and, optionally, glass tile components; Develop a ceramic package or Lower Tile Assembly (LTA) consisting of hermetically sealing a ceramic sidewall to a ceramic anode producing a single unit capable of housing the MCP stack up enabling development of a Gen II LAPPDTM having low loss, high bandwidth and mechanical robustness. The ceramic bodies used in this Task will be the same as in Task 1 and Task 3. Our goal was to work with commercial suppliers to economically fabricate the ceramic components; Evaluate alternative LAPPD top window materials to determine compatibility in sealing to the ceramic sidewall described in Task 2. Concurrently we will specify and select an alloy seal material suitable for sealing the top window to the sidewall, and we will perform sealing trials of these components; Demonstrate electrical characteristics of the inside-out anode in the detector context, the seal integrity of the bonded two-piece ceramic lower tile assembly (LTA) as well as the hermetic seal quality of the window to the sidewall; and Secure at least one specific NP, HEP or commercial application for a Gen II LAPPDTM enabled by this technology to be developed in Phase II.
