The ArDM project aims at measuring signals induced by WIMPs in a liquid argon detector. A 1-ton prototype is currently developed with the goal of demonstrating the feasibility of such a direct detection experiment with large target mass. The technical design of the detector aims at ind ependently measuring the scintillation light and the ionization charge originating from an interaction of a WIMP with an argon nucleus. The principle of the experiment and the conceptual design of the detector are described.4 pages, 1 figure, Invited talk at 2nd Workshop On TeV Particle Astrophysics, 28-31 August 2006, Madison, WI, USAHigh Energy Physics - Phenomenologytext
