Macro-pulse generation in a storage-ring free-electron laser : A single-particle plus FEL numerical approach
(2006) 10th European Particle Accelerator Conference, EPAC 2006 p.89-91- Abstract
In a storage-ring free-electron laser (FEL), the onset and growth of intra-cavity power at the resonator wavelength can be naturally accompanied by coherent emission at higher harmonics. Contrary to what happens in singlepass linac-based devices, the electron beam is re-circulated in the storage ring and, while the microbunching becomes "thermalized" from turn to turn, the evolution of other bunch properties has to be considered. As a consequence, a correct theoretical understanding of the process requires a proper modeling of turn-by-turn evolution of the electronbeam phase-space, both inside the undulators, where the FEL interaction takes place, and along the ring. To simulate this process we have coupled a modified version of the 3D... (More)
In a storage-ring free-electron laser (FEL), the onset and growth of intra-cavity power at the resonator wavelength can be naturally accompanied by coherent emission at higher harmonics. Contrary to what happens in singlepass linac-based devices, the electron beam is re-circulated in the storage ring and, while the microbunching becomes "thermalized" from turn to turn, the evolution of other bunch properties has to be considered. As a consequence, a correct theoretical understanding of the process requires a proper modeling of turn-by-turn evolution of the electronbeam phase-space, both inside the undulators, where the FEL interaction takes place, and along the ring. To simulate this process we have coupled a modified version of the 3D numerical code Ginger, which models the FEL interaction, together with a linear one-turn map, which propagates the electron beam along the ring. We present our results and a first benchmarking with experiments carried out using the Elettra storage-ring FEL.
