Abstract

Employing colliding-pulse injection has been shown to enable the generation of high-quality electron beams from laser–plasma accelerators. Here, by using test particle simulations, Hamiltonian analysis, and multidimensional particle-in-cell simulations, we lay the theoretical framework for spin-polarized electron beam generation in the colliding-pulse injection scheme. Furthermore, we show that this scheme enables the production of quasi-monoenergetic electron beams in excess of 80% polarization and tens of pC charge with commercial 10-TW-class laser systems.

碰撞脉冲注入方案中自旋极化电子束的产生

采用碰撞脉冲注入已被证明能够从激光等离子体加速器中产生高质量的电子束。本文通过实验粒子模拟、哈密顿分析和多维粒子池模拟，为碰撞脉冲注入方案中产生自旋极化电子束奠定了理论框架。此外，我们证明了该方案可以在商用10- tw级激光系统中产生超过80%极化的准单能电子束和数十个pC电荷。
