细胞内粒子模拟表明，利用相对论性自透明和空穴钻孔效应，可以很容易地在相对论性近临界密度等离子体中形成短空化通道。强自生磁场将电子限制在等离子体通道中。在磁场的辅助下，电子以共振频率与激光场共振
Particle-in-cell simulations suggest that a short cavitated channel in relativistic near-critical density plasma can be readily created by relativistic self-transparency and hole-boring effect. The strong self-generated magnetic fields confine the electrons in the plasma channel. Assisted by the magnetic fields, the electrons resonance with the laser fields at betatron resonance frequency
