abstract = {{Laser wakefield accelerators (LWFA) present great potential to drive a free-electron laser (FEL) in a compact footprint because of the extremely high accelerating gradient. However, there are still many obstacles to overcome before the LWFA-driven FEL device can truly achieve exponential amplification and saturated output. These problems include how to resolve the phase slippage effect caused by the fs-level length of LWFA beams, and how to stably generate high-quality beams and preserve the quality during the transport. In this presentation, a novel scheme of X-ray FEL based on cascaded LWFAs is proposed aiming at addressing the above issues. High-quality electron beams with stable central energy and relatively long beam length can be generated using staged LWFAs. With a dedicated beamline design, the longitudinal phase space, beam length and inter-stage coupling are optimized, and start-to-end simulations show that such beams can drive the XFEL to saturation. In addition, the proposed scheme also possesses the capability to adjust FEL radiation bandwidth through precise longitudinal phase space steering. Our scheme provides a highly viable new route to realize LWFA-driven compact XFEL devices.}},
