      abstract     = {A screening of oxygen profiles in mid-T treated SRF
                      cavities is crucial, in order to infer physical correlations
                      between the microscopic cavity lattice and cavity
                      performance – a problem concerning acceleration physicists
                      for years. This thesis provides an analysis of oxygen
                      diffusion profiles for three differently treated samples:
                      Two mid-T baked and the third with the standard EuXFEL
                      recipe. The measurement method utilizes EXAFS spectroscopy
                      and was carried out at the DELTA facility in Dortmund. The
                      result suffers heavily under noise, making the quantity of
                      the result barely useable. Qualitatively, no deviations of
                      current models regarding the profiles could be proven, and
                      no results of previous studies were contradicted. The
                      experimental analysis is described in precision,
                      interpretations of the possible are undertaken and
                      theoretical considerations regarding error estimation and
                      possible EXAFS simulations for future attempts are provided.
                      A repetition at the PETRA III facility is indicated.},
