Study of radon removal performance of silver-ion exchanged zeolite from air for underground experiments
T. Sone, Y. Takeuchi, M. Matsukura +6
Radon is a common background source for underground astroparticle physics experiments and its removal is essential. In this study, we fabricated several prototype silver-ion exchan…
Removal of Radioactive Noble Gas Radon from Air by Ag-Zeolite
H. Ogawa, Y. Takeuchi, H. Sekiya +6
This paper investigates the removal of radon from purified and ambient airs by Ag-zeolite. Ag-zeolite is known to have very high performance for airborne radon removal. The depende…
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…
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…
Improvement of radon detector performance by using a large-sized PIN-photodiode
K. Okamoto, Y. Nakano, G. Pronost +4
Radioactive noble gas radon () is one of the major background sources below the MeV region in rare event search experiments. To precisely measure radon concentra…
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…
Evaluation of radon adsorption efficiency values in xenon with activated carbon fibers
Y. Nakano, K. Ichimura, H. Ito +5
The radioactive noble gas radon-222 (, or Rn) produced in the uranium series is a crucial background source in many underground experiments. We have estimated th…
Measurement of the radon concentration in purified water in the Super-Kamiokande IV detector
Y. Nakano, T. Hokama, M. Matsubara +7
The radioactive noble gas radon can be a serious background source in the underground particle physics experiments studying processes that deposit energy comparable to its decay pr…
Measurement of Radon Concentration in Super-Kamiokande's Buffer Gas
Y. Nakano, H. Sekiya, S. Tasaka +4
To precisely measure radon concentrations in purified air supplied to the Super-Kamiokande detector as a buffer gas, we have developed a highly sensitive radon detector with an int…
Calibration of the Super-Kamiokande Detector
K. Abe, Y. Hayato, T. Iida +130
Procedures and results on hardware level detector calibration in Super-Kamiokande (SK) are presented in this paper. In particular, we report improvements made in our calibration me…
