    "abstract": "Energy recovering an electron beam after it has participated in a\nfree-electron laser (FEL) interaction can be quite challenging because of the\nsubstantial FEL-induced energy spread and the energy anti-damping that occurs\nduring deceleration. In the Jefferson Lab infrared FEL driver-accelerator, such\nan energy recovery scheme was implemented by properly matching the longitudinal\nphase space throughout the recirculation transport by employing the so-called\nenergy compression scheme. In the present paper,after presenting a\nsingle-particle dynamics approach of the method used to energy-recover the\nelectron beam, we report on experimental validation of the method obtained by\nmeasurements of the so-called \"compression efficiency\" and \"momentum\ncompaction\" lattice transfer maps at different locations in the recirculation\ntransport line. We also compare these measurements with numerical tracking\nsimulations.",
