Longitudinal Phase Space Manipulation in Energy Recovering Linac-Driven Free-Electron Lasers
Energy recovering [1] an electron beam after it has participated in a free-electron laser (FEL) interaction can be quite challenging because of the substantial FEL-induced energy spread and the energy anti-damping that occurs during deceleration. In the Jefferson Lab infrared FEL driver-accelerator, such an energy recovery scheme was implemented by properly matching the longitudinal phase space throughout the recirculation transport by employing the so-called energy compression scheme [2]- In the present paper, after presenting a single-particle dynamics approach of the method used to energy-recover the electron beam, we report on experimental validation of the method obtained by measurements of the so-called--compression efficiency--and--momentum compaction--lattice transfer maps at different locations in the recirculation transport line. We also compare these measurements with numerical tracking simulations.
