A setup for the realization of dual-phase experiments using xenon as the active medium in a radiation detector has been built. The setup consists of a gas purification system capable of achieving a purity of the gas in the ppb level and a chamber system consisting of an ionization chamber containing the sensitive elements and a cooling component used to reach cryogenic temperatures inside the chamber in the range of liquid xenon temperature. The main goal of the dual-phase experiments is the operation of gas electron multipliers (GEM) in a cryogenic environment similar to the conditions found in experiments aimed to detect the most promising candidate for dark matter, i.e. the lightest supersymmetric particle known as neutralino or WIMPS.
