      abstract     = {Short wavelength, high intensity Free Electron Lasers
                      (FELs) require a high brightness electron beam, i.e. the
                      beam should have small transverse and longitudinal sizes,
                      small divergence and energy spread and high peak current.
                      Therefore, the detailed characterization of the beam is
                      required.The Photo Injector Test facility at DESY, Zeuthen
                      site (PITZ), was established as a test stand of the electron
                      source for Free electron Laser in Hamburg (FLASH) and the
                      European X ray Free Electron Laser (XFEL). The PITZ beamline
                      consists of various types of diagnostic devices for the
                      detailed bunch characterization. Mainly, the transverse
                      phase space characterization is performed at PITZ, but
                      longitudinal phase space measurements are also of great
                      importance for full characterization of high brightness
                      electron bunches from the photo injector.One of the ways to
                      measure the longitudinal phase space of electron bunch is an
                      RF deflector. It deflects particles transversely with
                      respect to the movement direction of the bunch in a linear
                      dependence on their longitudinal coordinates within the
                      bunch. As a result it gives the possibility to perform
                      measurements of the bunch longitudinal properties in
                      combination with a following transverse beam
                      characterization. Using additionally a dispersive section
                      the longitudinal phase space can be obtained as well.Another
                      approach to measure the longitudinal phase space of the
                      bunch is a tomographic method based on measurements of the
                      momentum spectra while varying the electron bunch energy
                      chirp. The energy chirp at PITZ can be applied and changed
                      by varying the RF phase of the CDS booster – the
                      accelerating structure installed downstream the gun. The
                      resulting momentum distribution can be measured with a
                      dipole spectrometer downstream. As a result, the
                      longitudinal phase space at the entrance and exit of the CDS
                      booster can be reconstructed over a wide range of bunch
                      charges. In this thesis both methods for longitudinal phase
                      space measurements are described in detail. Measurement
                      techniques are introduced. Numerical simulations of the
                      measurements are performed and studied. Results of the first
                      longitudinal phase space measurements at PITZ using the
                      tomographic technique are presented.},
