Description
We present an all-metal RF load that uses a series of mode conversions within an overmoded planar waveguide to extend the device's effective electric length. We present devices with two, three, and four modes operating simultaneously to achieve uniform power absorption across the broad side of the planar waveguide. The guide is made of highly conducting material, copper or aluminum, with a few microns of 430 Stainless steel sputtered on its surface. The properties of this magnetic stainless steel were carefully characterized using special TE01 resonant cavities. In one incarnation of the device, the overall dimensions are relatively small, only 5 to 6 wavelengths in two dimensions, and about 2 wavelengths in the third. H-fields were calculated as point clouds for a 6 kW average power heat load. The H-field point clouds were converted to spatially dependent heat flux values and applied to the vacuum cavity walls. A cooling channel and manifold design is presented along with the full manufacturing ready prototype design.
