Phys. Rev. ST Accel. Beams 12, 071301 (2009) [6 pages]Wakefields in photonic crystal cavities
Simulations of charged particle beams in accelerator cavities show that a two-dimensional photonic crystal can be used to create a three-dimensional hybrid cavity with a single operating mode and no significant higher order modes, greatly reducing long-range wakefields. Optimizing the photonic crystal cavity to reduce radiation leakage in the desired mode (of a finite-sized structure) yields even lower wakefields. Wakefields in photonic crystal cavities are compared to those in metal pillbox cavities. This article is available under the terms of the Creative Commons Attribution 3.0 License.
