Title: Progress in the use of pixel detectors in double beta decay experiment TGV

The TGV collaboration has been investigating two neutrino double electron capture (2╬ŻEC/EC) in {sup 106}Cd since 2000. The double beta experiments would answer some of the puzzling problems about neutrinos (e.g. nature and mass) but one of the main challenges is the background events. The collaboration is investigating the use of pixel detectors in such rare decay experiments. Pixel detector gives spatial information along with energy of the particle, thus provides useful information to reduce the background. The collaboration has proposed a Silicon Pixel Telescope (SPT) for the next generation experiment; where a pair of Si pixel detectors with enriched Cd foil in the middle forms the detection unit. A prototype unit of SPT has been constructed and results of preliminary background measurements performed on the surface and in the underground laboratories are presented.
