Directional scintillation detector for the detection of the wind of WIMPs
arXiv:astro-ph/0207529 · doi:10.1016/S0168-9002(02)01661-3
Abstract
The quenching factor of the proton recoil in the stilbene scintillator was measured with a 252Cf neutron source and was found to be 0.1 - 0.17 in the recoil energy range between 300 keV and 3 MeV. It was found to depend on the direction of the recoil proton. The directional anisotropy of the quenching factor could be used to detect the wind of the WIMPs caused by the motion of the earth around the galactic center.
