Description
TREX-DM (TPC for Rare Event eXperiments-Dark Matter) at LSC is an experiment looking for low-mass WIMPs with a TPC equipped with large microbulk Micromegas. An update on the background after the installation of an improved version of the detectors is discussed, as well as the method developed to calibrate in the low-energy range (few and sub keV). Likewise, the latest R&D results using a GEM preamplification stage on top of the Micromegas detector are presented. These are very promising in terms of lowered energy threshold and improved sensitivity of the experiment.
