1. Development of high-sensitivity radon detector in water with continuous measurement

Author

Nakano, Yuuki, Takeuchi, Yasuo, Yamamoto, Shotaro, Takeda, Atsushi, and Okamoto, Kohei

Abstract

Radon contamination in pure water causes serious background for low energy physics in Super-Kamiokande experiment, especially, search for distortions of the solar neutrino energy spectrum induced by the MSW effect. For lowering energy threshold (currently 3.5 MeV kinetic energy), investigation of radon concentration in water with sensitivity of < 1 mBq/m3 level is important and a radon detector with sensitivity of ~0.1 mBq/m3 has been developed by using activated charcoal trap with some time delay. On the other hand, real-time monitoring of Rn concentration in water with < 1 mBq/m3 level is indispensable for more dense investigation including its time evolution. In this poster, development of high-sensitivity radon detector for water with continuous measurement is presented. It consists of existing 80 L radon detector for air with sensitivity < 1 mBq/m3 and a degasifier module located at optimized position to maximize detection efficiency.

Abstract

NEWAGE is a direction-sensitive dark-matter-search experiment that uses a micro-patterned gaseous detector, or ��-PIC, as the readout. The main background sources are ��-rays from radioactive contaminants in the ��-PIC. We have therefore developed a low-alpha-emitting ��-PICs and measured its performances. We measured the surface ��-ray emission rate of the ��-PIC in the Kamioka mine using a surface ��-ray counter based on a micro TPC., 6 pages, 4 figures

Abstract

Recent measurements at the T2K experiment indicate that CP violation in neutrino mixing may be observed in the future by long-baseline neutrino oscillation experiments. We explore the physics program of an extension to the currently approved T2K running of $7.8\times 10^{21}$ protons-on-target to $20\times 10^{21}$ protons-on-target,aiming at initial observation of CP violation with 3$\,\sigma$ or higher significance for the case of maximum CP violation. With accelerator and beam line upgrades, as well as analysis improvements, this program would occur before the next generation of long-baseline neutrino oscillation experiments that are expected to start operation in 2026., Comment: 18 pages, 4 figures

Abstract

The radioactivity background are among the most dangerous background for low energy neutrino analysis in Super-Kamiokande (SK), like the solar neutrino analysis. Among them, the main contribution is coming from $^{222}$Rn, which is spread in the detector's water due to the water source and to the photo multiplier (PMT) emanations. Up to now, its exact distribution in the detector was not known. Using our knowledge of the radon concentration in the detector water, and the SK-IV solar data, we developed a model of the radon distribution in the detector. The uncertainty on the Rn concentration associated with this model was estimated to be $\sim0.1$ mBq/m$^{3}$

Abstract

Super-Kamiokande (SK) is a 50-kt water Cherenkov detector, instrumented with $\sim 13$k photo-multipliers and running since 1996. It is sensitive to neutrinos with energies ranging from 4.5 MeV to several TeV. A new framework has been developed for the follow-up of gravitational wave (GW) alerts issued by the LIGO-Virgo collaboration (LVC). Neutrinos are searched for, using a 1000-second time window centered on the alert time and in both SK low-energy and high-energy samples. Such observation can then be used to constrain the neutrino emission from the GW source. The significance of potential signals has been obtained by comparing neutrino direction with the localization of the GW. The computation of limits on incoming neutrino flux and on the total energy emitted in neutrinos by the source has been performed for the different neutrino flavors. The results using the LVC GWTC-2 catalog (covering O3a period) are presented, as well as the outlooks for the future real-time public release of follow-ups for the O4 period (in 2022) and beyond.
