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…
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…
Scintillator ageing of the T2K near detectors from 2010 to 2021
The T2K Collaboration, K. Abe, N. Akhlaq +355
The T2K experiment widely uses plastic scintillator as a target for neutrino interactions and an active medium for the measurement of charged particles produced in neutrino interac…
First Gadolinium Loading to Super-Kamiokande
K. Abe, C. Bronner, Y. Hayato +212
In order to improve Super-Kamiokande's neutron detection efficiency and to thereby increase its sensitivity to the diffuse supernova neutrino background flux, 13 tons of $\rm Gd_2(…
The Hyper-Kamiokande Experiment -- Snowmass LOI
Kamiokande Collaboration, K. Abe, P. Adrich +387
Hyper-Kamiokande is the next generation underground water Cherenkov detector that builds on the highly successful Super-Kamiokande experiment. The detector which has an 8.4~times l…
