      abstract     = {PETRA III is a 6 GeV third generation synchrotron light
                      source in Hamburg, Germany. The storage ring is operated
                      with a typical beam current of 100 mA and is running in
                      top-up mode. The beam delivered to PETRA III is accelerated
                      by a fast cycling booster synchrotron (DESY II), extracted
                      in a 203 m long beam transport line (E-Weg) and injected
                      afterwards into PETRA III. In the framework of PETRA IV
                      upgrade scenarios the potential for decreasing the extracted
                      emittance from DESY II has been investigated which can be
                      achieved by lowering the extraction energy to 5 GeV and
                      increasing the focusing in DESY II. In addition measuring
                      the emittance of the extracted beam from DESY II and the
                      optics in the beam transport line can help to better
                      understand and improve the injection efficiency of PETRA
                      III. By changing the quadrupole strength and measuring the
                      beam size downstream on a screen monitor in the E-Weg the
                      emittance of DESY II and the Twiss functions at a quadrupole
                      in the E-Weg have been determined. Measurements at different
                      energies of DESY II will be shown and compared with
                      calculations.},
