Phase synchronization recovery in energy-compressed LWFA electron beams for free-electron lasers via undulator tapering

Shan-You Teng, Wai-Keung Lau, Shih-Hung Chen +1

Laser wakefield accelerators (LWFAs) are attractive compact drivers for free-electron lasers (FELs) because they can generate femtosecond electron beams with high peak current over…
