Directional scintillation detector for the detection of the wind of WIMPs

The quenching factor for proton recoils in a stilbene scintillator was measured with a 252 Cf neutron source and was found to be 0.1–0.17 in the recoil energy range between 300 keV and 3 MeV . It was confirmed that the light yield depends on the direction of the recoil proton. The directional anisot...

Description
Summary:The quenching factor for proton recoils in a stilbene scintillator was measured with a 252 Cf neutron source and was found to be 0.1–0.17 in the recoil energy range between 300 keV and 3 MeV . It was confirmed that the light yield depends 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.
