Universidad de Zaragoza Status of low mass WIMP detector TREX-DM 2019 Access copy available to the general public Unrestricted TREX-DM (TPC Rare Event eXperiment for Dark Matter) is a high-pressure Micromegas-based TPC designed to host a few hundreds of grams of light nuclei (argon or neon) with energy thresholds potentially at the level of 0.4 keVee or below. Preliminary background studies suggest that the levels expected are of the order of 1-10 counts keV-1 kg-1 d-1, making TREX-DM competitive in the search for low mass WIMPs (<10 GeV). The experiment has been approved by the LSC (Laboratorio Subterrneo de Canfranc) and the last months have been devoted to its installation underground. Here we will report on the first commissioning phase. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 0.227 2019 Physics and Astronomy (miscellaneous) 2019 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-6948-5101 Cebrián, S.
