The design and development of a 6 MeV X-band on-axis coupling standing wave linear accelerator

On the basis of an X-band 2 MeV on-axis standing wave electron linear accelerator, we design and develop a 6 MeV X-band on-axis SW accelerating guide that has higher effective shunt impedance. The phase-focusing and asymmetrical cell geometry in the first cavity techniques are used. The non-linearit...

Description
Summary:On the basis of an X-band 2 MeV on-axis standing wave electron linear accelerator, we design and develop a 6 MeV X-band on-axis SW accelerating guide that has higher effective shunt impedance. The phase-focusing and asymmetrical cell geometry in the first cavity techniques are used. The non-linearity of RF fields in the accelerating guide is considered. The design parameters of the accelerating guide, magnetron and thermionic cathode are described. This accelerator system operates in /spl pi//2 mode and its frequency is 9300 MHz. A prototype 376 mm long structure has been machined, brazed and sealed, and tested.
