000012528 520__ $$aThe objective of this study has been to analyse the pattern recognition potential for background discrimination in a high pressure Time Projection Chamber (TPC) equipped with Micromegas detectors looking for the 136Xe neutrinoless double beta decay (ββ0ν). In addition the commissioning of a medium size prototype equipped with pixelized Micromegas allows to do first recognition of tracks in long drift distances (38 cm) and to study the performance of these detectors on it. Results show good pattern recognition capabilities and energy resolutions, proven the operability of these detectors for a ββ0ν experiment. The study of the background rejection potential in a 100kg TPC operating with Xe gas at 10 bar and equipped with Micromegas to study the ββ0ν have been done with MonteCarlo simulations. After the application of discrimination algorithms based on pattern recognition a rejection power of six orders of magnitude was obtained while the signal efficiency is 40%.
