Description
Summary:A novel radio frequency quadrupole (RFQ) resonant structure with bent vanes is proposed at the Institute of Modern Physics, Chinese Academy of Sciences (IMP, CAS). Compared with the traditional four-vane type RFQs, the bent-vane type structure is more compact at low frequency with significant reduction in the cross section size, and is capable of using a simple cooling system due to its rotationally symmetric structure. An 81.25 MHz proof-of-principle cavity is now under development at IMP. The beam dynamics design, electromagnetic optimizations with multipacting simulations, multiphysics analyses, and mechanical design of this novel bent-vane type RFQ (BV-RFQ) will be presented in this paper.
