Funding: The reported study was funded by RFBR according to the research project 18-302-00990 Dual axis superconducting spoke cavity for Energy Recovery Linac application is proposed. Conceptual design of the cavity is shown and preliminary optimiza-tions of the proposed structure have been carried out to minimize the ratio of the peak magnetic and electric fields to the accelerating voltage. The new design and future work are discussed |

Asymmetric SRF Dual Axis Cavity for ERLs: Studies and Design for Ultimate Performance and Applications | |
|
||
| A dual axis asymmetric SCRF ERL has been recently proposed as a possible way to drive a high average current electron beam while avoiding the BBU instability excitation. Such high current ERLs can be attractive for the next generation light sources, beam cooling in electron ion collider and isotope production. Here the results of the studies of band-pass modes and HOMs will be shown. The field distribution of the modes will be shown and asymmetric field distribution of HOMs will be demonstrated and HOMs excitations using dipole couplers will be discussed. The original design of the dual axis asymmetric cavity has been optimised to minimize the peaks of magnetic and electric fields on the cavity surface, to increase the distance between operating mode and neighbouring parasitic mode as well as to reduce the cavity manufacturing cost. To reach the goals several solutions have been suggested leading to simplification of the manufacturing as well as bringing the fields amplitudes on the cavity surface to the acceptable values. The new design of the cavity will be presented and possible applications of such a high-current ERL will be discussed. | ||
