TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Atomic layer deposited functional nano-film technology is used to manufacture Microchannel plate (MCP) devices capable of high gain / low ion feedback operation, on glass capillary array substrates, as a means to replace MCP chevron configuration and enable direct photocathode deposition (e.g. GaN) for NASA applications. Commercial MCP devices rely on 1970's manufacturing technology, constrained by the bulk glass: heavy metal impurities limit the achievable dark noise in low signal detection, the requisite batch processing restricts flexibility to tailor individual device performance and often result in poor yield. Arradiance's proven nano-film technology has been shown in Phase I to improve the component functions of secondary electron emission and conductivity resulting in high performance MCPs. In Phase II performance optimization of these novel devices and, enabled by substrate independence, an opportunity to explore direct deposition of advanced photocathodes. Since the high quality GaN films required for efficient photoelectron transport can only be deposited at elevated temperatures (<900 C), conventional Pb-glass MCPs, with a softening point of ~400C, are not suitable. Arradiance nanofilms allow high temperature MCP substrates (e.g. quartz or anodized alumina - AAO) and the opportunity for significant detection efficiency improvement. TRL 4 at beginning; TRL 6 at end.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
NASA: Substrate independence, large area detectors, single event detection in a single MCP (no chevron required), greatly improved resolution and direct deposition of opaque photocathodes have the potential for enormous impact on NASA missions. These innovations will contribute to improved resolution and optics simplification. By significantly improving functionality & capability of MCPs, a single plate configuration capable of low noise, high resolution counting and imaging that could surpass existing detector performance benchmarks becomes possible. A significant reduction of size, mass, power and cost of detection enabling smaller, more affordable spacecraft while benefitting science measurement capabilities allowing NASA programs can to meet multiple mission needs making the best use of limited resources.
