Aiming to the high energy electron acceleration, we have performed both theoretical and experimental studies. A curved plasma channel has been proposed to guide intense lasers for multistage laser wakefield acceleration. In our recent experiment we found that when the channel curvature radius is gradually increased and the laser incidence offset is optimized, the stable laser guiding is possible and wakefields can be excited in the curved channel. Electrons with maximum energy of 0.7GeV have been observed. Our results show that such a channel exhibits good potential for seamless multi-stage laser wakefield acceleration. A 200+300TW two-laser system platform will be installed in SJTU. The research plans, such as staged wakefield acceleration, Thomson scattering and plasma optics studies on this platform, will be introduced. ER -
