Gas Shutter Closure for Sealing LOS (Lines of Sight) Pipes

摘要

An extensive effort went into the design and development of an extremely reliable gas shutter closure for use in sealing a line of sight pipe between a nuclear explosion and an experiment array. The type of event that would require a gas shutter has been out of vogue for many years, but recently there has been a renewed interest in vertical line of sight testing. This report documents some of the unwritten history of the valves before this history is completely forgotten. 3 figs. (ERA citation 13:018852)
