Understanding the mystery of dark matter is one of the biggest challenges in physics today. Direct detection of dark matter using low background underground detectors is one of the most promising path allows us to probe the nature of dark matter and the new physics beyond the Standard Model. Several detector technologies have been developed over the past decades. In this talk, I will focus on the dual-phase xenon Time Projection Chamber which take on leadership role in racing of hunting dark matter particles. The XENON1T experiment, which is the largest running liquid xenon detector for searching dark matter at Gran Sasso underground laboratory, sets the world leading limit on WIMP (Weakly Interacting Massive Particles) - nucleon scatter cross section based on this novel technology. The detector has been running in a stable condition for more than one year. The design and operation of the detector, as well as data analysis will be covered in this talk.
