Effects of initial spin orientation on the generation of polarized electron beams from laser wakefield acceleration in plasma
The effects of initial spin orientation on the final electron beam polarization in laser wakefield acceleration in a pre-polarized plasma are investigated theoretically and numerically. From the results of variation of the initial spin direction, the spin dynamics of the electron beam are found to depend on the self-injection mechanism. The effects of wakefields and laser fields are studied using test particle dynamics and particle-in-cell simulations based on the Thomas–Bargmann–Michel–Telegdi equation. Compared with transverse injection, longitudinal injection is found to be preferable for obtaining a highly polarized electron beam.
