Description
The large-scale Water-based Liquid Scintillator (WbLS) detector is a new opportunity for the neutrino community to accomplish competent long-baseline neutrino oscillation and unprecedented low-energy neutrino measurements. Several table-top WbLS detection systems have been implemented at BNL and LBNL.
It is critical to advance further with a mid-scale demonstrator to understand and tune the WbLS property and stability.
A 1-ton detector located at BNL instrumentation building, with WbLS contained in an acrylic tank that coupled with 2'' and 3'' PMTs outside, was built in 2022. In addition, a 30-ton detector at BNL, equipped with Hamamatsu 10'' PMTs submerged in the WbLS, is being built with the same team. Various liquid materials were developed and filled sequentially in the 1-ton detector. The performance and stability of WbLS for cosmic muons and an alpha source were measured with the 1-ton detector. In this presentation, the latest experiment's status and the physics results will be shown.
