Temporal Profile Measurements of Relativistic Electron Bunch Based on Wakefield Generation | |
|
||
| A full characterization of the beam longitudinal phase space is crucial for the optimization of the performances of Free Electron Laser facilities, which require very short bunches to reach the time resolution for experiments of physics, biology and material science. We studied a novel approach to perform time-resolved measurements of a relativistic electron bunch based on the self-transverse wakefield interaction of the beam itself passing off-axis through a dielectric-lined or corrugated waveguide. The method is passive, can reach sub-fs resolution, and does not suffer of jitter issues. The main limitation is the poor resolution at the head of the bunch. We present simulations and a proof-of-principle experiment carried out at the SwissFEL injector test facility as well. | ||
