      abstract     = {The goal of this dissertation was to investigate a reliable
                      single-shot pulse duration diagnostic tool for the pulse
                      duration and wavelength range delivered at the Free Electron
                      LAser of Hamburg (FLASH). At
                      Self-Amplified-Spontaneous-Emission-based free-electron
                      lasers (FELs), the radiation parameters - duration, arrival
                      time, energy, spectrum, and spatial distribution - differ
                      for each pulse. A dedicated single-shot diagnostic tool for
                      each parameter is therefore essential in order to interpret
                      the experimental data on a pulse-to-pulse basis.This work
                      summarizes the effort to realize a temporal diagnostic tool
                      using the streaking technique by building a terahertz (THz)
                      "streak camera". The setup was prepared and calibrated, and
                      various pulse duration measurements with different
                      experimental settings were performed in order to explore and
                      validate the application range of the streaking method. The
                      aspects limiting the temporal resolution using the
                      commissioned streaking setup were characterized
                      experimentally. The pulse duration measurements were
                      analyzed using classical and quantum mechanical streaking
                      theory models.Furthermore, a deep statistical study on the
                      SASE fluctuations was realized using single-shot
                      measurements of various radiation parameters. Scaling laws
                      were derived using theoretical simulations and the measured
                      data. This analysis enabled the intrinsic statistical SASE
                      fluctuations to be disentangled from accelerator-based
                      fluctuations and measurement uncertainties.},
