Dark Matter Search with Direction Sensitive Scintillator
نویسنده
چکیده
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 have performed a pilot experiment at Kamioka to prove the feasibility of this method.

Dark 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 کاملDark matter search experiment with CaF2(Eu) scintillator at Kamioka Observatory
We report recent results of a WIMP dark matter search experiment using 310g of CaF2(Eu) scintillator at Kamioka Observatory. We chose a highly radio-pure crystal, PMTs and radiation shields, so that the background rate decreased considerably. We derived limits on the spin dependent WIMP-proton and WIMP-neutron coupling coefficients, ap and an. The limits excluded a part of the parameter space a...
متن کاملDirect detection prospects of dark vectors with xenon-based dark matter experiments
Dark matter experiments primarily search for the scattering of WIMPs on target nuclei of well shielded underground detectors. The results from liquid scintillator experiments furthermore provide precise probes of very light and very weakly coupled particles that may be absorbed by electrons. In these proceedings we summarize previously obtained constraints on long-lived dark matter vector parti...
متن کاملCharge amplification concepts for direction-sensitive dark matter detectors
Direction measurement of weakly interacting massive particles in time-projection chambers can provide definite evidence of their existence and help to determine their properties. This article demonstrates several concepts for charge amplification in time-projection chambers that can be used in direction-sensitive dark matter search experiments. We demonstrate reconstruction of the “head-tail”ef...
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...
