Abstract

The design and implementation of an experimental setup are demonstrated for the breakdown testing of pressurized text{SF}-{6} (1-3 atm) at 2.85 GHz. Sulphur hexafluoride (text{SF}-{6}) is a common insulating gas used to mitigate breakdown in high power microwave systems. While this gas is known for its high dielectric strength, available data for the breakdown of pressurized SF 6 and text{SF}-{6} mixtures at S-Band frequencies is limited. The obtained breakdown characteristics are compared to mixtures of text{SF}-{6} and Nitrogen (mathrm{N}-{2}) for similarities in breakdown fields in a pressurized environment.
