Status of the TREX-DM experiment at the Canfranc Underground Laboratory 2020 Access copy available to the general public Unrestricted The TREX-DM experiment is conceived to look for low mass WIMPs by means of a gas time projection chamber equipped with novel micromegas readout planes at the Canfranc Underground Laboratory. The detector can hold 20 l of pressurized gas up to 10 bar, which corresponds to 0.30 kg of Ar, or alternatively, 0.16 kg of Ne. The micromegas will be read with a self-triggered acquisition, allowing for effective thresholds below 0.4 keV (electron equivalent). The preliminary background model, following a complete material screening program, points to levels of the order of 1-10 counts keV-1 kg-1 d-1 in the region of interest, making TREX-DM competitive. The status of the commissioning, description of the background model and the corresponding WIMP sensitivity will be presented here. info:eu-repo/grantAgreement/EC/FP7/240054/EU/Novel Developments in Time Projection Chambers (TPCs) for Rare Event Searches in Underground Astroparticle EXperiments/TREX info:eu-repo/grantAgreement/ES/MINECO/FPA2013-41085-P info:eu-repo/grantAgreement/ES/MINECO/FPA2016-76978-C3-1-P info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 0.21 2020 Physics and Astronomy (miscellaneous) 2020 Q4 info:eu-repo/semantics/conferenceObject info:eu-repo/semantics/publishedVersion Castel, J.
