 note = {In Japan we are conducting a laser-plasma acceleration (LPA) project aiming a compact X-ray free-electron laser (XFEL) system and a compact carbon ion injector for cancer therapy including efficient laser driver development. In this talk we will focus on the laser electron acceleration part. Our LPA electron beam platform is located in the SPring-8 Center site at RIKEN, Japan, where the prototype XFEL of SACLA was tested. In the platform a Ti:sapphire laser system is installed and it can deliver three synchronized laser pulses (~20 – 30 fs) with pulse energies of 1 J, 2 J, and 10 J. Our strategy is staged electron acceleration using these pulses by manipulating electron phase space to obtain monoenergetic electron beams.
In this talk we present our recent results on ~250 MeV, reproducible, quasi-monoenergetic electron production, undulator radiation test, etc.
