Outline of Final Research Achievements

We have developed a single phase liquid xenon dark matter detector in which direct scintillation light (S1) and proportional scintillation light (S2) utilized for precise position reconstruction. We have designed electrodes and electric fields designed for a future detector. We have also developed two types of test bench having an anode electrode either with a gold-coated10 micron tungsten-wire or with a electron-gas-multiplier (GEM) in order to measure S1 and S2 in the given range of planed electric fields. In the GEM setup, we tested previous report for observation of S2 signal with GEM in liquid xenon with a few kV for GEM voltage. But no S2 signal was observed with 36kV/cm in GEM.
