A fiducial mass of 1000 kg, distributed in ten independent liquid xenon time t s projection chambers(LXeTPCs) will be used to probe the lowest interaction cross a : section predicted by SUSY models. The TPCs are operated in dual (liquid/gas) v i phase, to allow a measurement of nuclear recoils down to 16 keV energy, via simul- X taneous detection of the ionization, through secondary scintillation in the gas, and r
