Towards a free-electron laser driven by a laser wakefield accelerator
… (FEL) is a powerful source of tuneable coherent radiation that currently demands kilometre-scale beam lines for high-energy vacuum ultraviolet (VUV) and X-ray output. Driving an FEL with a laser wakefield accelerator (LWFA) electron beam would radically reduce the size of such systems as well as …

Timing Diagnostics and Coherent Harmonics from a test-FEL
… were extracted in an APPLE-II type elliptical undulator. A thermionic gun with a barium oxide cathode was adapted for photocathode operation, and the performance of the gun was tested. Measurements showed the production of 200 pC of electrons with a normalized emittance of 5.5 mmmrad and a …
