Vacuum Insulator Failure Measurements and Improvement
Abstract
Cones, cylinders, and insulators have been tested with a 3 nanosecond full width halfmax pulse. These insulators were made of epoxy, acrylic, lexan, and nylon. The tests were conducted with cone insulators at +45 degrees, -45 degrees, and 0 degree. Additionally, tests were conducted with a plug in the anode that reduces the anode stress, and anodized cathodes. Best results were obtained with both an anodized cathode and an anode plug where failure was through the solid dielectric at 600 kV/cm. Results of this testing will be presented.
