Having an active volume of similar to 35 cm drift x 28 cm diameter, it constitutes the largest Micromegas-read TPC operated in Xenon ever constructed, made by a sectorial arrangement of the 4 largest single wafers manufactured with the Microbulk technique to date. It is equipped with a suitably pixelized readout and with a sufficiently large sensitive volume (similar to 23 l) so as to contain long (similar to 20 cm) electron tracks. First results obtained at 1 bar for Xenon and Trymethylamine (Xe-(2{\%}) TMA) mixture are presented. The TPC can accurately reconstruct extended background tracks. An encouraging full-width half-maximum of 11.6{\%} was obtained for similar to 29 keV gammas without resorting to any data post-processing.", optnote="WOS:000336123200070", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=1800), last updated on Wed, 17 Jul 2019 09:56:38 +0000", issn="1748-0221", doi="10.1088/1748-0221/9/03/P03010", opturl="http://arxiv.org/abs/1311.3242", opturl="https://doi.org/10.1088/1748-0221/9/03/P03010", archivePrefix="arXiv", eprint="1311.3242", language="English" }
