Research Abstract

In recent dark mater search experiments, liquid Xenon is being used. Because scintillation vacuum ultra violet light is used in the dark matter experiments, property of the light in the liquid xenon is getting important. In this research, monitoring system of scattering and absorption length in liquid xenon was developed.
