一种高效的超导腔设计方案

Efficient Design Scheme of Superconducting Cavity

Sang-ho Kim, Marc Doleans, Yoon Kang

摘要:

对于许多下一代高强度质子加速器应用,包括超导中子源(SNS),超导(SC)RF为直线加速器提供了技术选择。在设计超导腔时,需要考虑若干特征,例如峰值场、单元间耦合、机械刚度、场平坦度、外部Q、可制造性、分路阻抗、高阶模(HOM)等,应该一起考虑。通过探索整个腔体的几何空间,找到了一种确定最佳腔体形状的系统方法,通过调整单元形状,可以实现RF能量的最有效利用。在参数空间中找到了一个满足所有合理设计准则的小区域,简化了最优形状的选择。本文详细阐述了该优化方案的整个设计过程,并将其应用于SNS谐振腔的设计。

英文摘要:

For many next-generation high intensity proton accelerator applications including the Spallation Neutron Source (SNS), superconducting (SC) RF provides the technology of choice for the linac. In designing the superconducting cavity, several features, such as peak fields, inter-cell coupling, mechanical stiffness, field flatness, external Q, manufacturability, shunt impedance, higher order mode (HOM), etc., should be considered together. A systematic approach to determine the optimum cavity shape by exploring the entire geometric space of the cavity has been found. The most efficient use of RF energy can be accomplished by adjusting the cell shape. A small region in parameter space satisfying all reasonable design criteria has been found. With this design procedure, choosing the optimum shape is simplified. In this paper, the whole design procedure of this optimisation scheme is explained and applied to the SNS cavity design.
