      abstract     = {Medium temperature (mid-T) heat treatments at about 300 °C
                      are used to enhance the intrinsic quality factor of
                      superconducting radio frequency (SRF) cavities.
                      Unfortunately, such treatments potentially increase the
                      sensitivity to trapped magnetic flux and consequently the
                      surface resistance of the cavity. For this reason, it is
                      crucial to maximizethe expulsion of magnetic flux during the
                      cool down. The flux expulsion behavior is next to the heat
                      treatment mainly determined by the geometry, the niobium
                      grain size and thegrain orientation. However, it is also
                      affected by parameters of the cavity performance tests like
                      the cool down velocity, the spatial temperature gradient
                      along the cavity surface andthe magnetic flux density during
                      the transition of the critical temperature. To improve the
                      flux expulsion behavior and hence the efficiency of future
                      accelerator facilities, the impact of these adjustable
                      parameters as well as the mid-T heat treatment on 1.3 GHz
                      TESLA-Type single-cell cavities is investigated by a new
                      approach of a magnetometric mapping system. In this
                      contribution first performance test results of cavities
                      before and after mid-T heat treatment are presented},
