Development of a C-band High Gradient Accelerating Structure Prototype
The development of a C-band high gradient acceleration structure is introduced.Through the use of low group velocity,4π/5 working mode,equal gradient structure,arched cavity and large beam aperture,creative internal water-cooled tunable cavity structure,suspension welding method and other technologies,the engineering application of the first C-band high gradient acceleration structure section in China is achieved.A C-band accelera-ting gradient of 50.8 MV/m is achieved in beam tests,which is the highest in the world.
