With the stat-of-the-art laser technique, the quality of electron beam generated from laser-plasma accelerator (LPA) is now becoming much more better. The natural merits LPA beam, e.g. high peak current, ultra-low emittance and ultra-short bunch length, etc., pave the way to the novel light sources, especially in the realm of developing much compact X-ray light sources, e.g. table-top X-ray free-electron laser, although the radiation power is limited by the rather larger energy spread than conventional LINAC. Luckily, much more power could be extracted by using the undulator with transverse gradient (TGU) when energy spread effect could be compensated. Here we introduce a novel soft x-ray light source driven by LPA based on TGU technique. Meanwhile we present a simple idea on how to achieve much higher rep-rate (e.g. ~100 kHz) storage ring based FELs boosted by TGU.

Free electron laser, as the fourth generation of light source, has been developed for decades, the higher power, ultrafast pulse in femtosecond scale, better spectral resolution were achieved. It has been approved a powerful tool in the scientific researches, perfect complement of tabletop laser system and synchrotron light source. FEL in EUV range, especially around 100nm, is very helpful to investigate the chemical reactions in the basic energy research, because the small molecule or radical, related to combustion, can be ionized and detected efficiently and sensitively by intense EUV beam with one photon. A new project to generate EUV beam from 50 to 150 nm at Dalian, Dalian Coherent Light Source (DLCS), was advocated by Dalian Institute of Chemical Physics & Shanghai Institute of Applied Physics. The coherent optical beam with more than 100uJ per pulse will be achieved with high gain harmonic generation1 and well controlled in femtosecond time scale2. User experimental stations in the studies of molecular beams and surface dynamics will also be built at the same time. A conceptual design of DLCS and related research plans will be present at the conference.
