      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
                      wakefield 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 plasma 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 gas targets of high density are employed. In
                      these proceedings we further present that the polarization
                      of protons in HT and HCl gas targets is largely conserved
                      during laser wake-field acceleration, even if the proton
                      energies enter the multi-GeV regime. Such polarized sources
                      for electrons, protons, deuterons and 3He ions are now being
                      built in Jülich. Proof-of-principle measurements at the
                      (multi-)petawatt laser facilities PHELIX (GSI Darmstadt) and
                      SULF (Shanghai) are in preparation.},
