We are developing such system based on staging laser acceleration at LAPLACIAN, RIKEN SPring-8 center aiming for future compact X-ray free-electron lasers (XFELs). In staging acceleration, several separate-function
stages are employed as standard radio-frequency linear accelerators. We start experiments with two-stages: an electron injector and a booster accelerator.
Because the beam quality even with state-of-art LWFA is not sufficient for XFELs, we need further improvement as well as reproducibility. To mitigate this issue we consider beam matching between stages as indispensable. We are developing plasma monitors and electron beams monitors. The details of the developed devices will be presented.
