Development of a method to measure trace level of uranium and thorium in scintillation films
K. Ichimura, K. Chiba, Y. Gando +7
We have established a method to measure picograms-per-gram (pg g) levels of U and Th in scintillation films by combining the dry ashing method and inductivel…
Second gadolinium loading to Super-Kamiokande
K. Abe, C. Bronner, Y. Hayato +246
The first loading of gadolinium (Gd) into Super-Kamiokande in 2020 was successful, and the neutron capture efficiency on Gd reached 50\%. To further increase the Gd neutron capture…
Present status of PICOLON project
K. Fushimi, D. Chernyak, H. Ejiri +24
The existence of cosmic dark matter and neutrino properties are long-standing problems in cosmology and particle physics. These problems have been investigated by using radiation d…
Rapid Analysis of in Ultrapure Gadolinium Sulfate Octahydrate
Y. Sakakieda, K. Hosokawa, F. Nakanishi +6
Numerous particle physics experiments utilize gadolinium (Gd), a rare earth element with the most significant neutron capture cross-section among all elements, to detect anti-neutr…
Development of Ultra-pure Gadolinium Sulfate for the Super-Kamiokande Gadolinium Project
K. Hosokawa, M. Ikeda, T. Okada +20
This paper reports the development and detailed properties of about 13 tons of gadolinium sulfate octahydrate, , which has been dissolved into…
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…
