Abstract :
The development is complete on a load to dissipate 2-MW continuous wave of RF power at frequencies above 100 GHz and transmitted in the HE11 waveguide. A rotating launcher distributes the RF power inside the load and prevents excessive localized heating from constructive interference. The load design also minimizes reflected power. Two loads are currently in operation in Japan, and the performance results are presented. A new version is in development for the ITER facility in France.
