Stable Electron Beams by Laser Wakefield Acceleration (LWFA) and the ImPACT Program in Japan | |

Funding: This work is funded by ImPACT Program of Council for Science, Technology and Innovation (Cabinet Office, Government of Japan), and was partly supported by Core Research of Evolutional Science and Technology (CREST) of Japan Science and Technology Agency (JST). A laser wakefield acceleration (LWFA) research that aims at table-top sized free-electron laser (FEL) under the ImPACT program in Japan will be reviewed. LWFA is expected to be a novel scheme for accelerating electron beams beyond GeV-class energy with compact devices. In recent studies, the pointing stability of the electron beams from LWFA has been dramatically improved by plasma-micro-optics (PMO) that is plasma device functioning as a focusing and optical-guiding tool for intense laser pulses. The PMO enables electron beams to be precisely controlled and/or transported by the beam-optics of conventional accelerators. With these techniques a staging LWFA has been demonstrated successfully, and high quality quasi-mono-energetic beams below the 100 MeV range are produced with good repeatability as an injector. Sub-GeV electron beams are also produced with a 4 mm-booster laser wakefield. These results will be presented and discussed. A future experimental site at SPRING-8/RIKEN is being prepared for the exclusive use of the laser-driven FEL. The plans towards a test area on the laser-driven FEL at SPRING-8 /RIKEN will be presented. |

The Horizon 2020 Project EuPRAXIA ('European Plasma Research Accelerator with eXcellence In Applications') aims at producing a design report of a highly compact and cost-effective European facility with multi-GeV electron beams using plasma as the acceleration medium. The accelerator facility will be based on a laser and/or a beam driven plasma acceleration approach and will be used for photon science, high-energy physics (HEP) detector tests, and other applications such as compact X-ray sources for medical imaging or material processing. EuPRAXIA started in November 2015 and will deliver the design report in October 2019. EuPRAXIA aims to be included on the ESFRI roadmap in 2020. | ||
