Direction-sensitive Dark Matter Search –NEWAGE–

Directional information should play a significant role for a firm detection of the galactic dark matter. We developed a prototype three-dimensional gaseous tracking device for a direction-sensitive dark matter direct detection. We investigated the performance of the prototype detector and demonstrated a direction-sensitive dark matter search experiment in a surface laboratory. We set the first limit on the spin-dependent WIMP (Weakly Interacting Massive Particles)-proton cross s ection by a direction-sensitive method.
