      abstract     = {Polarised beams are indispensable for many experiments in
                      particle,atomic and nuclear physics where spin-dependent
                      processes are to be studied.The LEAP (Laser Electron
                      Acceleration with Polarisation) project at DESYaims to
                      generate and measure spin-polarised electron beams from a
                      compactlaser plasma accelerator (LPA) for the first time.
                      The generation of spin-polarised beams from an LPA relies on
                      a pre-polarised plasma source, wherehydrogen halide
                      molecules are dissociated by a circularly polarised UV
                      laserpulse. The dissociation of an HCl gas target requires a
                      laser pulse with a wave-length of about 200 nm, which has to
                      be synchronised with the LPA driver laser,as the
                      depolarisation of the electrons in the gas occurs in the
                      sub-nanosecondrange. Therefore, the UV pulse will be
                      generated by cascaded second harmonicgeneration of the
                      fundamental 800 nm LPA driver pulse. This contributionwill
                      give an overview of the LEAP project and the experimental
                      progress ofpreparing a pre-polarised plasma source for LPA.},
