The development of a 340GHz modified sine waveguide vacuum electron amplifier is presented here. Output power from this structure is predicated to exceed 10W with a pencil beam electron gun at 17 kV and 38mA. Design, fabrication and test of slow wave structure (SWS) and pillbox window are discussed respectively. The cold test results show a good agreement with the simulation, which verified the properties of low loss and wide bandwidth of the high frequency system.
