Present methods of accelerating charged particles such as electrons depend upon so called accelerators. Previous research has shown interaction of intense laser radiation with a plasma that can accelerate electrons to very high energies. The researchers are carrying out more detailed studies on the coupling of laser energy to electron plasma waves and are investigating the effect of plasma parameters such as electron density, density gradient, turbulence, and scale length on the acceleration of electrons. The experimental data being acquired should provide insight into onset, growth, and saturation of electron plasma waves driven by intense radiation (laser). The experiments also provide graduate student experience in optics, lasers, particle acceleration, parmetric processes, electrical discharges in gases as well as theoretical and computational explanation of the observation.

现有的加速带电粒子如电子的方法 依赖于所谓的加速器。 先前的研究表明 强激光辐射与等离子体的相互作用， 将电子加速到非常高的能量。 研究人员正在 进行更详细的研究激光能量的耦合， 电子等离子体波，并正在研究等离子体的影响 参数，如电子密度，密度梯度，湍流， 电子加速的尺度长度。 实验数据 获得应该提供洞察发病，生长， 强辐射驱动的电子等离子体波饱和 （激光）。 实验还提供了研究生的经验， 光学、激光、粒子加速、参数过程、电气 气体放电以及理论和计算 观察的解释。
