      abstract     = {Magnetic flux trapped in the niobium bulk material of
                      superconducting radio frequency (SRF) cavities degrades
                      their quality factor and the accelerating gradient. The
                      sensitivity for flux trapping is mainly determined by the
                      treatment and the geometry of the cavity as well as the
                      niobium grain size and orientation. To potentially improve
                      the flux expulsion characteristics of SRF cavities and hence
                      the efficiency of future accelerator facilities, further
                      studies of the trapping behavior are essential. For this
                      purpose a magnetometric mapping system to monitor the
                      magnetic flux along the outer cavity surface of 1.3 GHz
                      TESLA-Type single-cell SRF cavities has been developed and
                      is currently in the commissioning phase at DESY. Contrary to
                      similar approaches, this system digitizes the sensor signals
                      already inside of the cryostat to extensively reduce the
                      number of required cable feedthroughs. Furthermore, the
                      signal-to-noise ratio (SNR) and consequently the measuring
                      sensitivity can be enhanced by shorter analog signal lines,
                      less thermal noise and the Mu-metal shielding of the
                      cryostat. In this contribution test results gained by a
                      prototype of the mapping system are presented.},
