Pumping Effectiveness of a Magnesium Vapor Jet in the Presence of a High Power Neutral Beam Source

摘要

An experimental study of a superconic magnesium vapor jet neutralizer has established the effectiveness of the jet in reducing cold streaming gas from a high current neutral beam source. The removal of molecular hydrogen gas by a magnesium jet neutralizer provides a means of simplifying beamline design by improved pumping characteristics of the jet compared with conventional technology while simulataneously improving performance.
