dc.description.abstract [EN] NEXT-MM is a general-purpose high pressure (10 bar, ∼25 l active volume) Xenon- based TPC, read out in charge mode with an 0.8 cm×0.8 cm-segmented 700 cm2 plane (1152 ch) of the latest microbulk-Micromegas technology. It has been recently commissioned at University of Zaragoza as part of the R&D of the NEXT 0νββ experiment, although the experiment s first stage is currently being built based on a SiPM/PMT-readout concept relying on electroluminescence. Around 2 million events were collected during the last months, stemming from the low energy γ -rays emitted by a 241 Am source when interacting with the Xenon gas (Eγ = 26, 30, 59.5 keV). The localized nature of such events above atmospheric pressure, the long drift times, as well as the possibility to determine their production time from the associated α particle in coincidence, allow the extraction of primordial properties of the TPC filling gas, namely the drift velocity, diffusion and attachment coefficients. In this work we focus on the little explored combination of Xe and trimethylamine (TMA) for which, in particular, such properties are largely unknown. This gas mixture offers potential advantages over pure Xenon when aimed at Rare Event Searches, mainly due to its Penning characteristics, wave-length shifting properties and reduced diffusion, and it is being actively investigated by our collaboration. The chamber is currently operated at 2.7 bar, as an intermediate step towards the envisaged 10 bar. We report here its performance as well as a first implementation of the calibration procedures that have allowed the extension of the previously reported energy resolution to the whole readout plane (10.6% FWHM@30 keV) es_ES

DE-AC02- 05CH11231; and the Portuguese FCT and FEDER through the program COMPETE, projects PTDC/FIS/103860/2008 and PTDC/FIS/112272/2009. J. Renner (LBNL) acknowledges the support of a US DOE NNSA Stewardship Science Graduate Fellowship under contract no. DE-FC52- 08NA28752. The development of NEXT-MM in particular has important contributions from the European Research Council T-REX Starting Grant ref. ERC-2009-StG-240054 of the IDEAS program of the 7th EU Framework Program; and also MINECO under grants FPA2008-03456, FPA2011-24058 and CPAN under grant CSD2007- 00042. This work would not have been possible without the encouragement of our RD51 colleages and the dedicated effort of R. de Oliveira and his team at CERN to provide these unique detectors. Discussions with O. Sahin, R. Veenhof, S. Biagi and C. Acevedo are greatly acknowledged. DGD gratefully acknowledges the ‘Charpak award’ for this work.
