Abstract
Incom Inc. is developing and commercializing a new type of microchannel plate (MCP) electron multiplier, as well as MCP-based photodetectors such as the Large-Area Picosecond Photodetector, LAPPD(TM), and the High-Resolution Picosecond Photodetector, HRPPD. This new class of MCPs is called “ALD-GCA-MCPs” because these are MCPs that are made from glass capillary arrays (GCA) – glass plates with a regular array of hollow glass capillaries – that are functionalized using atomic layer deposition (ALD) thin film coating technology. ALD-GCA-MCPs are a technology advancement that affords MCPs with significantly improved performance, as compared to conventional MCPs. We will provide a brief ALD-GCA-MCP technology overview highlighting the current state of the art of Incom’s ALD-GCA-MCP technology, as well as ongoing developments addressing the GCA glass substrate, the resistive and secondary-electron-emissive ALD coatings, and their implications for detectors used in astronomical applications.
