Sano). In staged acceleration experiments, precise alignment of electron and laser beams is necessary. Spatial profiles of electron with the resolution of a few micrometers, a timing monitor, and a pulse duration monitor are necessary to have good phased acceleration of electrons. In addition, the laser position monitors are also important to a closed loop to maintain the spatial and temporal overlap the interaction. In the presentation, the diagnostics for beam monitor is discussed., Optics & Photonics International Congress 2016 (High Energy Density Science 2016)}, title = {Beam diagnostics for staged laser electron acceleration experiments}, year = {2016} }
