X Band Linear Accelerator Magnetrons

Advances in technology have now made possible the production of portable x-ray machines based on linear accelerators. Operating at X-band these can be broken down into suitcase sized components. The microwave power source has to fit into one of these components but still produce high peak and mean powers. This paper describes work carried out at EEV on the first tunable X-band magnetrons designed specifically for this purpose. Despite their small size they have the highest power level of any tunable X-band magnetron yet made.
