Abstract:

The report describes an enclosed spark gap light source designed to be operated in a low pressure environment. While the light intensity from an open spark gap is greatly reduced at lower ambient pressures, the enclosed spark gap system maintains a constant light intensity through a range of ambient pressures from 760 millimeters to 100 microns of Hg. In addition, other electrical problems that occur at reduced pressures are eliminated. Author
