通过理论和粒子模拟研究了斜激波俘获电子的机理。推导了能量方程,重点关注粒子速度和平行于磁场 B 的电场。然后表明,电子可以通过 F 的负倾角来反射,其中 F 是平行电场沿 B 的积分,E‖=(E∙B)∕B。反射后,由于 F 恢复为正值,平行能量减少。这导致深度电子捕获。这些理论预测已通过相对论电磁粒子模拟得到验证。
The mechanism of electron trapping by an oblique shock wave is studied with theory and particle simulations. An energy equation is derived, which focuses on particle velocity and electric field parallel to the magnetic field B. It is then shown that electrons can be reflected by a negative dip of F, where F is the integral of the parallel electric field, E‖=(E∙B)∕B, along B. The parallel energy is decreased after the reflection owing to the recovery of F to positive values. This leads to deep electron trapping. These theoretical predictions are verified with relativistic, electromagnetic particle simulations.
