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…
Development of low-background photomultiplier tubes for liquid xenon detectors
XMASS Collaboration, K. Abe, Y. Chen +36
We successfully developed a new photomultiplier tube (PMT) with a three-inch diameter, convex-shaped photocathode, R13111. Its prominent features include good performance and ultra…
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…
A measurement of the scintillation decay time constant of nuclear recoils in liquid xenon with the XMASS-I detector
XMASS Collaboration, K. Abe, K. Hiraide +35
We report an in-situ measurement of the nuclear recoil (NR) scintillation decay time constant in liquid xenon (LXe) using the XMASS-I detector at the Kamioka underground laboratory…
Development of low radioactivity photomultiplier tubes for the XMASS-I detector
XMASS Collaboration, K. Abe, K. Hiraide +39
XMASS-I is a single-phase liquid xenon detector whose purpose is direct detection of dark matter. To achieve the low background requirements necessary in the detector, a new model…
