Laser wakefield acceleration (LWFA) research has been conducted mainly for basic science which include
understanding acceleration mechanism in relativistic plasma, but it is now shifting to the research
for realization of laser-driven accelerators. In this paper, we introduce the current status of LWFA research
aimed at demonstrating laser-driven X-ray free electron laser (XFEL) under MIRAI-program at
RIKEN Harima campus, and outline the current status of research and development toward the stable
LWFA accelerator for practical use.
