| Outline of Final Research Achievements |
Many observations suggest that elementary particles called dark matter exist in the universe, but their identities are completely unknown. It is advantageous to use xenon to detect dark matter, and all the world leading experiments that are searching for dark matter use dual phase xenon detectors. In such detectors, electrons generated by elementary particles there are drifted by the electric field to the region of the upper gas xenon, and are amplified. While, this study aims at further increasing the sensitivity of dark matter search by using only liquid xenon.We succeeded in generating electron amplification in liquid xenon during the research period and has begun developing special electrodes for future large scale detector.
