This presentation is for the lowest energy physics in Super-Kamiokande, solar neutrino. SK detects 8B solar neutrinos through neutrino-electron elastic scattering, where the energy, direction, and time of the recoil electron are measured. Since SK-III started, many efforts to reduce backgrounds have been made. The most serious background comes from the beta decay of 214Bi, which is produced in...

Presentation
An unknown source of bubble nucleation is impacting the sensitivity of the bubble chambers of the PICO dark matter search. After the end of the current PICO runs assays have shown contamination with particulates. The present hypothesis is that these residual particulates which are small enough in size to remain suspended in the liquid are a dominant contributor of this nucleation. We have...

Presentation
Metal-doped liquid scintillator plays a key role in various particle and nuclear physics experiments. The applications of different metallic ions in solar and reactor neutrinos and in double beta decay searches and their purification methods will be discussed in this talk.

Presentation
A large capacity purification plant and fluid handling system has been constructed for the SNO+ neutrino and double-beta decay experiment, located 6800 feet underground at SNOLAB, Canada. SNO+ is a refurbishment of the SNO detector to fill the acrylic vessel with liquid scintillator based on Linear Alkylbenzene (LAB) and 2 g/L PPO, and also has a phase to load nature tellurium into the...
