As in a real experiment, we perform plasma density scanning for typical 100 TW laser facilities. Several basic laws for self-injected acceleration in a bubble regime are presented. According to these laws, we choose a proper plasma density and then obtain a high quality quasi-monoenergetic electron bunch with a rms energy of more than 650 MeV and a bunch length of less than 1.5 μm.展开更多

文摘In this paper, 2-D Particle-In-Cell simulations are made for Laser Wakefield Accelerations （LWFA）. As in a real experiment, we perform plasma density scanning for typical 100 TW laser facilities.
