      abstract     = {In this work an approach to relativistic electron
                      acceleration employing laser-driven dielectric
                      microstructures (DLA) is considered. New DLA designs were
                      developed, a simulation code for efficient DLA simulation
                      was devised, the capabilities of dielectric microstructures
                      as particle beam diagnostic devices were investigated and a
                      laser induced damage threshold measurement setup was
                      implemented and tested.To leverage well developed
                      near-infrared laser sources new DLAs were designed that are
                      robust against realistic manufacturing tolerances and
                      exhibit a predicted increased electron transmission of up to
                      $\SI{44}{\percent}$ of the charge and longitudinal
                      acceptance of around $\SI{2}{\femto\second},$ but are still
                      able to produce $\SI{}{\giga\volt/\meter}$ acceleration
                      gradients. A great challenge is the numerical simulation of
                      long interaction lengths of electrons with the short drive
                      laser wavelengths present in DLAs due to the high demand in
                      computation resources needed by the large simulation domain
                      compared to the wavelength. A novel method was developed,
                      which is able to efficiently model meter long DLAs without
                      any resonant particle approximations by use of transfer maps
                      generated from a single-period electromagnetic field
                      simulation and a limited set of particle tracking
                      simulations. In PIC simulations hundreds of DLA periods can
                      be modeled using a high performance computing cluster. With
                      the code presented in this work a meter long DLA (hundred
                      thousands of periods) can be simulated on a workstation.
                      This PhD work includes the numerical investigation of
                      particle beam diagnostics capabilities of DLAs, namely as
                      transverse deflecting structures and as new passive and
                      active bunch length measurement devices for ultra-short
                      particle bunches in the sub-femto second regime. All the
                      presented methods are very compact in the particle beam line
                      compared to existing methods.An experiment was devised to
                      test the designed DLAs by injection of an electron bunch
                      from a conventional state-of-the-art radio frequency
                      accelerator with the potential to show first increase of the
                      average energy of a relativistic electron beam in a DLA
                      device. In contrast all experiments up to today are only
                      modulating the particle beam energy. Finally an experimental
                      setup was designed and implemented to measure the short
                      pulse laser induced damage threshold of DLAs with
                      characterization measurements taken on a bulk material.},
