摘要：
我们提出一种可行方案，通过用于超相对论无偏振电子束与超强圆偏振激光脉冲单次碰撞的滤片机制，直接对相对论电子束进行偏振，并获得各种方向上的整体偏振。电子被散射到几度的大角度范围内，且电子的偏振状态与其碰撞后的空间位置相关。因此，我们可以采用滤片根据位置滤除部分散射电子，并为滤除后的电子束获得高整体偏振度。通过考虑自旋的 Monte-Carlo 模拟，在目前可实现的激光强度下，滤除后的电子束获得了在任意横向方向上高达 62% 的偏振度以及高达 10% 的纵向偏振。我们理论分析了散射电子的分布形成，并通过模拟研究了不同初始参数的影响，以证明我们方案的鲁棒性。该方案提供了一种简单灵活的方法，用于产生各种偏振方向的相对论偏振电子束。
英文摘要：
We propose a feasible scenario to directly polarize a relativistic electron beam and obtain overall polarization in various directions through a filter mechanism for single-shot collision between an ultrarelativistic unpolarized electron beam and an ultraintense circularly polarized laser pulse. The electrons are scattered to a large angular range of several degrees and the polarization states of the electrons are connected with their spatial position after the collision. Therefore, we can employ a filter to filter out a part of the scattered electrons based on their position and obtain high-degree overall polarization for the filtered beam. Through spin-considered Monte-Carlo simulations, polarization with a degree up to 62% in arbitrary transverse directions and longitudinal polarization up to 10% are obtained for the filtered beams at currently achievable laser intensity. We theoretically analyze the distribution formation of the scattered electrons and investigate the influence of different initial parameters through simulations to demonstrate the robustness of our scheme. This scenario provides a simple and flexible way to produce relativistic polarized electron beams for various polarization directions.
