线性激发等离子体中外注入电子加速的数值模拟
Simulations of the Acceleration of Externally Injected Electrons in a Plasma Excited in the Linear Regime
摘要:
用数值方法研究了10个高电荷\si{MeV}电子聚束(\SI{> 100}{pc})与激光产生的加速等离子体波的耦合。结果表明,使用\SI{50}{TW},\SI{100}{\micro \meter}宽激光束,在\SI{1}{ GV/m}上方产生加速场,可以实现高效耦合。我们提出了一个实验,可以测试这些预测。
英文摘要:
We have investigated numerically the coupling between a 10 \si{MeV} electron bunch of high charge (\SI{> 100}{pc}) with a laser generated accelerating plasma wave. Our results show that a high efficiency coupling can be achieved using a \SI{50}{TW}, \SI{100}{\micro \meter} wide laser beam, yielding accelerating field above \SI{1}{ GV/m}. We propose an experiment where these predictions could be tested.
