Abstract
Effects of the microwave magnetic field on window breakdown were investigated at the upstream and downstream side of a dielectric interface. Simple trajectory calculations of secondary electrons in an rf field show significant forward motion of electrons parallel to the microwave direction of propagation. The Lorentz-force due to the microwave magnetic field on high-energy secondary electrons might substantially influence the standard multipactor mechanism. As a result, the breakdown power level for the downstream side of a window would be higher than for the upstream side. This was tested utilizing an S-band travelling wave resonant ring, powered by a 3 MW magnetron at 2.85 GHz, leading to a total power greater than 60 MW.
