abstract = {The generation of polarized particle beams still relies on
conventional particle accelerators, which are typically very
large in scale and budget. Concepts based on laser-driven
wake-field acceleration have strongly been promoted during
the last decades. Despite many advances in the understanding
of fundamental physical phenomena, one largely unexplored
issue is how the particle spins are influenced by the huge
magnetic fields of the plasmas and, thus, how highly
polarized beams can be produced. The realization of
laser-plasma based accelerators for polarized beams is now
being pursued as a joint effort of groups from
Forschungszentrum Jülich (Germany), University of Crete
(Greece), and SIOM Shanghai (China) within the ATHENA
consortium. As a first step, we have theoretically
investigated and identified the mechanisms that influence
the beam polarization in laser-plasma accelerators. We then
carried out a set of Particle-in-cell simulations on the
acceleration of electrons and proton beams from gaseous and
foil targets. We could show that intense polarized beams may
be produced if pre-polarized targets of high density are
employed. Such polarized sources for electrons, protons,
deuterons and 3He ions are now being built in Jülich.
Proof-of-principle measurements at the (multi-)PW laser
facilities PHELIX (GSI Darmstadt) and SULF (Shanghai) are in
preparation.},
