Abstract: (IOP)

A technical description of NEXT-MM and its commissioning andfirst performance is reported. Having an active volume of~ 35 cm drift × 28 cm diameter, it constitutes thelargest Micromegas-read TPC operated in Xenon ever constructed, madeby a sectorial arrangement of the 4 largest single wafersmanufactured with the Microbulk technique to date. It is equippedwith a suitably pixelized readout and with a sufficiently largesensitive volume ( ~ 23 l) so as to contain long ( ~ 20 cm)electron tracks. First results obtained at 1 bar for Xenon andTrymethylamine (Xe-(2%)TMA) mixture are presented. The TPC canaccurately reconstruct extended background tracks. An encouragingfull-width half-maximum of 11.6 % was obtained for ~ 29 keVgammas without resorting to any data post-processing.
