【 摘 要 】

Liquid argon is known to be an excellent target material for WIMP dark matter direct search experiment. Since PY2012, we are working on a new dark matter search project (ANKOK) at Waseda university using the double phase argon detector technique. As a first stage of the project, we are currently concentrating our effort on improvement of the scintillation light detection efficiency so that the experiment has better sensitivity for low mass down to 10 GeV/c2WIMP. In this report, we describe R&D status of the ANKOK experiment.
