Outline of Final Research Achievements

We have developed a high-sensitivity radon detector (80L detector) to assay reaming radon in purified rare gases. We have lowered background level of the 80L detector. The achieved background level of the 80L detector is 0.81±0.08 (count/day). This level is about 1/3 of that of the previous radon detector. The basic performances are obtained in Ar gas and in Xe gas. This will enable us to apply the 80L detector to a dark matter search experiment with rare gas and so on. In a dark matter search experiment, XMASS, a real-time measurement device to assay radon in purified water is newly developed in this research, then started its operation.
