A high power millimeter wave generator has been investigated and improved by particle in cell(PIC) simulations and experiments. Overmoded slow wave structures(SWSs) were adopted to increase power capacity. In order to realize single mode and single frequency operation, one useful method for mode selection was used, i.e. to shift the operating point close to π mode of TM01 wave. Due to the adoption of overmoded SWSs and proper design of the device, the guiding magnetic field could be reduced. The experiments were carried out at the TORCH-01 accelerator. The produced microwave frequency was measured by dispersive line method, and the power was estimated by integrating over the radiation pattern in far field. Rectangular-shaped SWSs were used in primary design, and a 33.56 GHz millimeter wav
