英文摘要	The production of GeVelectron beam with narrow energy spread and high brightness is investigated using particle-in-cell simulations. A controlled electron injection scheme and a method for phase-space manipulation in a laser plasma accelerator are found to be essential. The injection is triggered by the evolution of two copropagating laser pulses near a sharp vacuum-plasma transition. The collection volume is well confined and the injected bunch is isolated in phase space. By tuning the parameters of the laser pulses, the parameters of the injected electron bunch, such as the bunch length, energy spread, emittance and charge, can be adjusted. Manipulating the phase-space rotation with the rephasing technique, the injected electron bunch can be accelerated to GeV level while keeping relative energy spread below 0.5% and transverse emittance below 1.0 mu m. The results present a very promising way to drive coherent x-ray sources.; National Basic Research Program of China [2013CBA01502]; National Natural Science Foundation of China [11575011, 11535001]; National Grand Instrument Project [2012YQ030142]; UK EPSRC [EP/G054950/1, EP/G056803/1, EP/G055165/1, EP/M022463/1]; SCI(E); ARTICLE; hylu@pku.edu.cn; x.yan@pku.edu.cn; 9; 19
