Research Institution
The single bunch beam breakup (BBU) instability is a potentially serious limitation on the performance of advanced accelerators, particularly those based on the wakefield principle. Development of mitigation techniques for BBU requires both experiment and high performance simulation tools. This project will study three representative high performance wakefield devices using new diagnostics. An advanced simulation code to model these experiments is being developed. The combined results from the experiments and simulations will enable the design of focusing systems to control BBU in wakefield devices. The Phase I project developed new software for rapid, efficient simulation of beam breakup effects in advanced linear accelerators. Simulations of the beam breakup experiments planned for Phase II, a 26 GHz high power extractor, transformer ratio enhancement and high gradient device experiments, were performed. Two different beam diagnostics were developed, a heterodyne differential probe and a beam spot moment diagnostic. During Phase II, the two new diagnostics for transverse deflection effects will be implemented at Argonne. These will be used to measure beam dynamics effects in advanced dielectric accelerating structures. Improvements to the code will be made and simulation results compared to experiments. Commercial Applications and other Benefits as described by the awardee: The tools developed under this project will enable the design and operation of high performance wakefield accelerators, primarily for physics research but also for industry and medical applications.
