Description
We present some important results related to Micromegas-TPC development for rare event detection: First, we show the influence of the detection plane structure on the energy resolution, where, replacing the wires planes (MWPC) by the Micromegas micropattern, gave a high collection efficiency with good uniformity and good energy resolution. Second, we prove that the increase of the height of the amplification zone permits a good charge collection at higher gas pressure. Third, we present a new gas mixture 'Xe(98)CF4(2)', which is convenient for the search of neutrinoless double beta decay in 136Xe. Fourth, large size Micromegas, with 50 cm of diameter is operated in the Gotthard-TPC (200 l) and showed high efficiency and good energy resolution with low energy sources
