Application of microwave technology in the accelerating tube of medical electron linear accelerator

Objective：To learn and master the application of microwave technology in medical electron linear accelerator tube. Methods： Introduced the structure and principle of medical electron linear accelerator, traveling wave accelerating tube and standing wave accelerating tube;compared the structure, stable system and transport system of traveling wave accelerating tube standing wave accelerating tube. Results：standing wave accelerating cube have higher efficiency, shorter accelerating cube and electron gun, but have higher demand for pulse modulator, automatic frequency stabilization, the deflection system and microwave transmission systems. Traveling wave accelerating cube have lower efficiency, but have better energy spectrum and easy to adjust. Conclusion：Both traveling wave accelerating cube and standing wave accelerating cube were used in medical electron linear accelerator nowadays, it＆#39;s easy to master medical electron accelerator after knowing the application of microwave in medical electron linear accelerator.
