TREX-DM: a low-background Micromegas-based TPC for low-mass WIMP detection
If Dark Matter is made of Weakly Interacting Massive Particles (WIMPs) with masses below $${\sim }20$$ GeV, the corresponding nuclear recoils in mainstream WIMP experiments are of energies too close, or below, the experimental threshold. Gas Time Projection Chambers (TPCs) can be operated with a variety of target elements, offer …
