12.2: A 350 MHz, 200 kW CW, multiple beam IOT

Design is complete and fabrication and assembly are progressing on a 350 MHz, 200 kW CW multiple beam inductive output tube (IOT). The device includes seven electron guns in a circular array. A single input cavity drives the fields for all seven electron guns. RF power is generated in a single output cavity. The device is predicted to achieve approximately 70% efficiency with 22 dB gain.
