Abstract
For over three years, the XENON100 experiment set the benchmark sensitivity for the weakly interacting massive particle (WIMP) dark matter candidate, with a crosssection of 2.0 x 10-45 cm2 at 55 GeV for spin independent interactions. In this thesis various analysis are introduced to extend the dark matter search with the XENON100 detector. For the science data taken in 2013/2014, studies on the light and charge yield as well as an optimized correction for the secondary scintillation signal is introduced, resulting in an increased energy resolution of the detector. Secondly, a method to determine the charge yield for electromagnetic interactions in liquid xenon with the XENON100 detector is developed and results are presented. Finally, a method is used to derive bounds on the WIMP - nucleus interactions, free of astrophysical uncertainties.
