Beam manipulation for compact laser wakefield accelerator based free-electron lasers by A Loulergue, M Labat, C Evain, C Benabderrahmane, V Malka, M E Couprie

“…After the success of FELs based on conventional acceleration using radio-frequency cavities, an important challenge is the development of FELs based on electron bunching accelerated by a laser wakefield accelerator (LWFA). However, the present LWFA electron bunch properties do not permit use directly for a significant FEL amplification. …”

Low density plasma waveguides for multi-GeV laser Wakefield accelerators by Picksley, A

“…These machines, however, are becoming increasingly large, technically challenging to construct, and uneconomical. Laser wakefield accelerators (LWFAs) provide immense accelerating fields, and offer the potential to reduce the size of particle accelerators by a factor of 1000, though several challenges are yet to be overcome. …”
