1.3GHz Inductive Output Tube for Particle Accelerators

There is an increasing requirement within the particle accelerator community for CW RF power sources in the L-band frequency range. The paper describes the development of a new inductive output tube (IOT) for use in high energy applications. A target specification of 16kW CW output power at an efficiency of 60% was set and this paper presents results obtained to date. The tube uses an electron gun geometry that minimizes transit time effects in the cathode to grid gap and draws heavily on e2v technologies’ expertise in the design and manufacture of IOT’s and klystrons.
