The Long Life Microchannel Plate is a new version of the microchannel plate. The glass structure is specially formulated for high temperature processing. It offers superior electrical characteristics. Its features are:
1. Longevity - substantially greater electrical stability of the strip current and gain.
2. Superior dark noise to that of the standard microchannel plate. 3. Can be recycled more than the standard microchannel plate.
4. Can be vacuum baked at higher temperatures for optimum tube outgassing and better performance.
In-house MCP electrical life test has shown that in three separate experimental cycles, Long Life Microchannel Plates are substantially more stable than our standard microchannel plates. The U. S. Army's Night Vision Laboratories have evaluated two tubes with L2 MCPs. The results were: superior MCP electron gain, better strip current and dark noise than a tube which was built with a standard microchannel plate.
