ABSTRACT

Laser-wakefield acceleration (LWFA), providing potentially jitter-free sources of radiation and electrons, is one of the rapidly developed scientific fields. Staging LWFA is considered to be a necessary technique for developing full-optical high energy electron accelerators. Splitting of the acceleration length into several technical parts and with independent laser drivers allows not only the generation of stable, reproducible acceleration fields but also overcoming the dephasing length while maintaining an overall high acceleration gradient and a compact footprint. The Laser Acceleration Platform is a unique experimental platform specially designed for laser wake-field acceleration research, which is located in the RIKEN SPring-8 center, Harima, Hyogo Prefecture, next to the 8 GeV storage ring and SACLA linear accelerator and XFEL. In this presentation, we will introduce our recent progress in this platform, mainly on the staging LWFA and undulator radiation.
