Improved method for measuring low concentration radium and its application to the Super-Kamiokande Gadolinium project
S. Ito, K. Ichimura, Y. Takaku +8
Chemical extraction using a molecular recognition resin named "Empore Radium Rad Disk" was developed to improve sensitivity for the low concentration of radium (Ra). Compared with…
Development of a method for measuring rare earth elements in the environment for future experiments with gadolinium loaded detectors
S. Ito, T. Okada, Y. Takaku +7
Demand to use gadolinium (Gd) in detectors is increasing in the field of elementary particle physics, especially neutrino measurements and dark matter searches. Large amounts of Gd…
Development of the measurement for radium using germanium detector with molecular recognition resin
S. Ito, K. Ichimura, Y. Takaku +3
High-purity germanium (HPGe) detectors are widely used for the measurement of the low concentrated radioactivities. For the Super-Kamiokande-Gadolinium project, the concentration o…
Determination of Trace Levels of Uranium and Thorium in High Purity Gadolinium Sulfate Using ICP-MS with Solid-Phase Chromatographic Extraction Resin
S. Ito, Y. Takaku, M. Ikeda +1
The new Super-Kamiokande-Gadolinium (SK-Gd) project is an upgrade of the Super-Kamiokande (SK) detector. In the SK-Gd project, 0.2\% Gd(SO) is loaded into the 50 kton w…
