不同等离子体密度绝热减稀模式加速电子
Laser Electron Accelerator in Plasma with Adiabatically Attenulating Density of Different Modes
【摘要】 就密度减稀等离子体中激光驱动尾场加速电子方案,尝试不同的等离子体密度减稀模式进行模拟计算,考察不同的密度减稀模式对电子加速的影响。模拟结果表明密度减稀尾场加速机制的存在和优越性,也表明适当设计密度减稀尾场加速电子方案可以得到能量高、电荷量大、能散度低的高品质电子束;模拟结果也说明密度减稀尾场加速电子机制的充分发挥并不要求很高的激光强度,方便从实验上进行验证。
【Abstract】 Theelectron acceleration mechanism in a wake of the plasma with a variety of adiabatically attenuating density modes is checked by numerical simulation.The simulation results prove that the new electron acceleration mechanism owing to the density attenuating is operated well,and the properly choice of the density attenuating mode can greatly improve the quality of accelerated electrons beam.And the results indicate that the efficiency of the electron acceleration mechanism in a wake of the plasma with a variety of adiabatically attenuating density modes is not dependent on the very high intensity of the laser.Experimental verification is convenient.
【Key words】 electron acceleration in a wake; plasma; adiabatically attenuating density; numerical simulation;
