Description
In recent years, sources of polarized beams from laser-plasma interaction have gained significant interest in the accelerator community [1]. Possible applications of such beams range from basic research, e.g. deep-inelastic scattering, to enhanced energy production in fusion reactors. It was shown by Kulsrud et al. that in the case of the reaction $d + t\to \alpha + n$, the cross-section is increased by a factor of 1.5 [2]. Similar enhancements are expected for other reactions like proton-Boron fusion.
In this talk, we present the state-of-the-art for polarized beams from plasma-based accelerators. In particular, we discuss recent theoretical results like the acceleration of polarized Helium-3 using Laguerre-Gaussian laser pulses as well as the first successful acceleration of polarized beams using the PHELIX laser system [3].
