Electron self-injection and acceleration in a hollow plasma channel driven by ultrashort intense laser pulses
Deng Suhui, Liu Mingping †
The distributions of electrons at t=2.8 ps with density ne=0.001nc (a), ne=0.002nc (b), ne=0.003nc (c), and ne=0.005nc (d), respectively. The dashed lines show the boundaries of the hollow plasma channel.
