The double beta decay (ββ) is a very challenging subject in today’s physics. It can be used as a powerful tool to test neutrino properties (e.g. if neutrino is Dirac or Majorana type) and lepton number conservation. However, these experiments demand very high sensitivity and very strong background reduction. New experimental approaches are necessary for satisfying such demands. Pixel detectors offer new possibilities in this direction, as it can better identify the background events and increase the efficiency of measurement. Timepix detector from Medipix collaboration is currently under investigation for two double beta decay experiments (TGV and COBRA). A new coincidence setup, pixel telescope (with detectors face to face) has been constructed and extensive background measurements were performed. Main tasks of this work were to propose and construct a suitable pixel detector setup for double beta measurements, understand the background radiation in the pixel setup and to suppress them. The preliminary results obtained from the background measurements (surface and underground) using newly developed setups as well as the estimation of the experimental limits for double beta decay which can be achieved using this unique detection technique are presented.
