      abstract     = {The acceleration of polarized electrons and protons in
                      strong laser and plasma fields is a very attractive option
                      to obtain polarized beams in the GeV range. We investigate
                      the feasibility of particle acceleration in strong fields
                      without destroying an initial polarization, taking into
                      account all relevant mechanisms that could cause
                      polarization losses, i.e. the spin precession described by
                      the T-BMT equation, the Sokolov-Ternov effect and the
                      Stern-Gerlach force. Scaling laws for the (de-)polarization
                      time caused by these effects reveal that the dominant
                      polarization limiting effect is the rotation of the single
                      particle spins around the local electromagnetic fields. We
                      compare our findings to test-particle simulations for high
                      energetic electrons moving in a homogeneous electric field.
                      For high particle energies the observed depolarization times
                      are in good agreement with the analytically estimated ones.},
