| Outline of Final Research Achievements |
R&D for the multipurpose detector for neutrino less double beta decay using xenon, dark mater search using noble gas, and pp solar neutrinos observation was performed. The plastic scintillator vessel in which TPB wavelength shifter was melted was developed. The wavelength shifted scintillation light of liquid xenon was detected using photomultiplier tubes. It has been demonstrated that ultra-low background can be achieved by utilizing the difference in emission waveform between plastic scintillator and liquid xenon.
