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…
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…
Development of a low--emitting -PIC as a readout device for direction-sensitive dark matter detectors
Takashi Hashimoto, Kentaro Miuchi, Tomonori Ikeda +10
Direction sensitivity could provide robust evidence for the direct detection of weakly interacting massive particles constituting dark matter. However, the sensitivity of this meth…
Anisotropic Response Measurements of ZnWO Scintillators to Neutrons for Developing the Direction-Sensitive Dark Matter Detector
Juan W. Pedersen, Hiroyuki Sekiya, Koichi Ichimura
The scintillation yields of ZnWO crystals change depending on the incident direction of particles. This property can be used as a direction-sensitive dark matter detector. So,…
Development of Dual-phase Xenon TPC with a Quartz Chamber for Direct Dark Matter Search
Kazufumi Sato, Masaki Yamashita, Koichi Ichimura +6
The idea of a hermetic quartz chamber in a dual-phase xenon time projection chamber (TPC) has the potential to improve the detector sensitivity for direct dark matter searches in t…
