Abstract
The ANKOK project is a new dark matter search experiment in Japan using the double phase liquid argon detector which is specialized for the low mass (~10 GeV/c2) WIMP detection. We
are currently proceeding R&D efforts to establish its physics sensitivity, such as understanding of the liquid argon scintillation and ionization processes for very low energy deposition (~20 keV) and development of the new photo-sensor which has direct sensitivity for the 128 nm VUV light.
In the next few years, we are targeting to construct a detector with fiducial mass of several tens of
kg, and to collect the underground physics data to search for the low mass WIMP.
