Abstract
We developed a three-dimensional gaseous tracking device, and performed a direction-sensitive dark matter search in a surface laboratory. By using 150 torr carbon-tetrafluoride (CF4gas), we obtained a sky map drawn with the recoil directions of the carbon and fluorin e nuclei, and set the first limit on the spin-dependent WIMP (Weakly Interacting Massive Particles)-proton cross s ection by a direction-sensitive method.
