AI Article Synopsis
- A new model for accelerating particles is introduced, focusing on how random disturbances in laser fields impact the process.
- Simulations reveal that plasma electrons can gain energy significantly surpassing the expected levels, highlighting the model's effectiveness.
- The study also finds that the self-generated magnetic field not only helps to keep the electron beams tight but also boosts their acceleration, leading to the creation of extremely high-energy electrons.
Article Abstract
A simple direct acceleration model is proposed, taking into account the stochastic phase disturbance of the coherent driving laser fields. A relativistic single particle simulation shows that plasma electrons are efficiently accelerated far above the ponderomotive energy. The energy and momentum distributions of the accelerated electrons are derived to examine the effects of the self-generated magnetic field on the characteristics of the electron beams. In addition to the beam collimation effect, the magnetic field is found to further enhance the electron acceleration, resulting in the generation of ultrahigh energy electrons.
