Research on Electron Linear Accelerators with Traveling Wave Resonators

The principle of electron linear accelerators with traveling wave resonators is described. The characteristics of this type of accelerator are analysed and calculated by means of the theory of the traveling wave resonator. To make this type of accelerator realistic, the simplified rf resonant ring is presented. A model has been tested at the low power. The measure results agree with the theory. Finally, a design example is presented. When a 2MW magnetron is used as a power source, the length of the accelerator structure is 300 mm or so, and the pulse current is 150 ma, the electrons will be accelerated to 4 Mev.
