A Project of a New Detector for Direct Dark Matter Search: MACHe3
2001
MACHe3 (MAtrix of Cells of superfluid 3He) is a project of a new detector for direct Dark Matter (DM) search. A cell of superfluid 3He has been developed and the idea of using a large number of such cells in a high granularity detector is proposed. This contribution presents, after a brief description of the superfluid 3He cell, the simulation of the response of different matrix configurations allowing to define an optimum design as a function of the number of cells and the volume of each cell. The exclusion plot and the predicted interaction cross-section for the neutralino as a photino are presented.
