Optimized Wakefield computations using a network model

PDF Version Also Available for Download.

Description

During the course of the last decade, traveling wave accelerating structures for a future Linear Collider have been the object of intense R and D efforts. An important problem is the efficient computation of the long range wakefield with the ability to include small alignment and tuning errors. To that end, SLAC has developed an RF circuit model with a demonstrated ability to reproduce experimentally measured wakefields. The wakefield computation involves the repeated solution of a deterministic system of equations over a range of frequencies. By taking maximum advantage of the sparsity of the equations, they have achieved significant performance … continued below

Description

During the course of the last decade, traveling wave accelerating structures for a future Linear Collider have been the object of intense R and D efforts. An important problem is the efficient computation of the long range wakefield with the ability to include small alignment and tuning errors. To that end, SLAC has developed an RF circuit model with a demonstrated ability to reproduce experimentally measured wakefields. The wakefield computation involves the repeated solution of a deterministic system of equations over a range of frequencies. By taking maximum advantage of the sparsity of the equations, they have achieved significant performance improvements. These improvements make it practical to consider simulations involving an entire linac ({approximately} 10{sup 3} structures). One might also contemplate assessing, in real time, the impact of fabrication errors on the wakefield as an integral part of quality control.
