This paper outlines the vision for a solid-state directional detector of weakly interacting massive particles (WIMPs) that integrates real-time event registration, three-dimensional directional information and high-density target material.
Significance and Impact
Directional detectors improve sensitivity to WIMP dark matter and overcome the challenge of irreducible neutrino background. A future WIMP detector will leverage or motivate advances in multiple disciplines toward precision dark matter and neutrino physics.
- The detector operates in hybrid mode: nuclear recoil event registration is performed in real-time using charge, phonon or photon collection.
- The solid-state detector using quantum defects in diamond would provide timing information and complete three-dimensional information via head/tail asymmetric signals.
