Final Report for "Advanced Modeling Tools for Optimizing Tapering Schemes in X-Ray Free-Electron Lasers"
- RadiaSoft, LLC, Boulder, CO (United States)
The primary goal of this project is to design, optimize, and understand beam dynamics issues with the Tapering-Enhanced Stimulated Superradiant Amplification (TESSA) advanced tapering scheme for high-efficiency FEL operation. The original Phase I narrative emphasized an advanced hybrid Vlasov approach for high-fidelity free-electron laser modeling with complex initial phase space distributions that include a variety of physical effects. After the period of performance began, RadiaSoft joined a collaboration with Argonne National Laboratory, UCLA, and RadiaBeam to build a TESSA experiment in the Linac Extension Area (LEA) at Argonne. The start-to-end simulations for a TESSA experiment became a major priority for the Phase I, with the hybrid Vlasov algorithm to be developed over the Phase II and a heavier overall emphasis on supporting the TESSA proof-of-concept experiment. During the first eight months, we developed start-to-end simulations of the LEA beamline for UCLA collaborators to run their TESSA simulations; derived a symplectic map approach to the FEL equations of motion; and developed a novel concept for Vlasov algorithms applicable to FEL modeling.
