Study of Breakdown/arcing for High Power RF Antennas on Fusion Applications
Abstract
dc:descriptionCCl4 and XeF2 were used as sources of halogen ions to take advantage of the ion bombardment for breakdown amelioration by modification of the electrodes. It was found that CCl4 stabilizes the emission current but increases the enhancement factor of copper electrodes. XeF 2 exhibits a self-extinguishing emission current behavior on copper and tungsten electrodes, which allows the electrodes to achieve higher hold-off voltages. To reveal the mechanism by which chemicals modify field emitters on high voltage electrodes a different system with ultra high vacuum, and in-situ diagnostics is required. Further study is recommended.
