Searching direction dependent daily modulation in dark matter detectors
arXiv:0807.3758
Abstract
Channeling of recoil ions in various crystals strongly depends on their direction. This, along with the WIMP wind due to the rotation of the galactic disc generates {\it daily} modulations of the channeling. Since channeling affect the characteristics of the WIMP induced recoil events these modulations may be observed in single crystal detectors and serve as a WIMP signature. We suggest in particular searching for such modulations in the DAMA scintillation data.
