Dark Matter Search with Direction Sensitive Scintillator
A direction sensitive dark matter detector using organic crystals is being developed. It exploits the anisotropic scintillation efficiency of organic crystals with respect to the direction of nuclear recoils relative to crystallographic axes. A variation of about 7% was observed in the scintillation efficiency of carbon recoils in a stilbene crystal for recoil energies of 30 keV to 1MeV. We hav...
متن کاملDark Matter Search with Direction Sensitive Scintillators
We have carried out the dark matter search with a 116g direction-sensitive stilbene crystal in Kamioka Observatory. With the crystal fixed to the earth, we searched the modulation of the light output. No modulation signal was found due to the small size of the detector crystal and the higher background rate yet to be eliminated. However, it demonstrated the effectiveness of the method of direct...
متن کاملPrototype Direction-Sensitive Solid-State Detector for Dark Matter.
A prototype weakly interacting massive particle (WIMP) detector system is described. The detection efficiency is much larger when the incident neutral particle flux is perpendicular to the detector plane than when it is parallel to the plane. A greatly scaled-up system based on this device would therefore be sensitive to the diurnal rotation of the “WIMP wind” produced by the solar system’s rap...
متن کاملDirection-sensitive dark matter search results in a surface laboratory
We developed a three-dimensional gaseous tracking device and performed a directionsensitive dark matter search in a surface laboratory. By using 150 Torr carbontetrafluoride (CF4) gas, we obtained a sky map drawn with the recoil directions of the carbon and fluorine nuclei, and set the first limit on the spin-dependent WIMP (Weakly Interacting Massive Particles)-proton cross section by a direct...
متن کاملDetector performance of the NEWAGE experiment
NEWAGE(NEw generation WIMP search with an Advanced Gaseous tracking device Experiment) project is a direction-sensitive dark matter search experiment with a gaseous micro time-projection-chamber(µ-TPC). We report on the performance of the µ-TPC with a detection volume of 23 × 28 × 30 cm 3 operated with a carbon-tetrafluoride (CF 4) of 0.2 bar.
