Abstract
Abstract
Water-based liquid scintillators (WbLS) are a new class of
detector materials that provide efficient and tunable detection of
both Cherenkov and scintillation light. A massive WbLS neutrino
detector with suitable photosensor coverage for low intensity light
detection could therefore reconstruct the momentum of an energetic
charged particle and also have enhanced low-energy sensitivity.
These materials are also better suited for metal doping broadening
the potential scientific utility. We recently constructed and
commissioned a 1-ton WbLS detector with good photosensor coverage
and a capable data acquisition and calibration system. We intend to
use this flexible detector system as a testbed for WbLS R&D. In
this paper we give an overview of the 1-ton system and provide some
early results.
