C波段高梯度加速结构样机研制

Development of a C-band High Gradient Accelerating Structure Prototype

本文介绍了C波段高梯度加速结构研制的内容,通过采用低群速度、4π/5工作模式、等梯度结构、拱形腔和大束流孔径设计方法、创造性的内水冷可调谐腔体结构、悬挂式焊接方法等技术,实现了国内第一支C波段高梯度加速结构段的工程应用,在束流试验中获得了50.8 MV/m的世界最高C波段带束加速梯度。

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 accelerating gradient of 50.8 MV/m is achieved in beam tests,which is the highest in the world.
