摘要:
在激光等离子体相互作用中对自注入电子束的加速及其对尾场的影响进行了理论研究.自注入电子束在空泡底部削弱了激光尾波静电场.随着自注入电子束电荷密度的增加,尾波场结构明显改变和空泡纵向变长.随后的鞘层电子须以较高的初始纵向动量才能自注入到不断演化的空泡尾场中.当自注入电子束的库仑场大于空泡内静电场时,该电子束将驱动等离子体尾波场.
Abstract:
The acceleration of a self-injected electron and its effect on the wakefield evolution during the laser-plasma interaction have been investigated.The space-charge electric field near the bubble bottom would be weakened by the self-injected electron bunch.The wakefield structure is strongly modified and the bubble elongates as the density of the self-injected electron bunch increases.The subsequent sheath electrons can be self-injected into the evolving bubble with higher initial longitudinal momentum.The self-injected electron bunch drives a plasma wakefield when its Coulomb field overwhelms the space-charge electric field of the bubble.
