Özet:
In this work, a general overview of the CAST experiment is given, and solutions to the specific problems that arose during the preperation time for the Phase II is explained, as well as the steps that were taken to reach the solutions. The analysis procedures of the collected data are also mentioned. Apart from a theoretical introduction about the axion particle and dark matter, a background on the CERN laboratory is presented as well. The detectors of CAST are described in detail, with their working principles, geometries, shielding materials, analysis programs and the results obtained from their data collected during the 2003 data taking period.
