Ultra-High Vacuum Systems for Gigawatt HPM Generation.
Abstract
The DURIP funds have been spent on several ultra high vacuum systems important to the advance of high power microwave generation. Novel oxide cathodes have been fabricated in our vacuum-arc plasma deposition chamber that produce high emission densities of 20 A/cm2 and display low work functions of only 1.6eV, which were made possible by the low vacuum pressures produced by the equipment purchased under the DURIP grant. Two Cusp electron guns have been delivered to UC Davis by Northrop Grumman. These state-of-the-art electron gunds will be employed to drive UC Davis' efficient high harmonic gyrotrons and peniotrons.
