SULFUR HEXAFLUORIDE IN HIGH-POWER MICROWAVE SYSTEMS

Abstract

Sulfur hexafluoride is being used extensively as a means of obtaining high peak power performance in waveguide systems. There is reason to believe that optimum efficiency is not currently being achieved in waveguide systems using this electronegative gas. This report reviews that available data on the use of SF6 in microwave systems. Inconsistencies in these data are noted. For example, power ratios (breakdown power of SF6 over that of air at normal pressures with all other parameters constant) are reported from a low of 3 to a high of 40. The mechanisms of these inconsistencies are discussed in terms of geometric configuration, contamination, localized hot spots, localized corona discharge, etc. Areas of future investigation are discussed.
