  Water-based liquid scintillators (WbLS) are attractive neutrino detector
materials because they allow us to tune the ratio of the Cherenkov and
scintillation signals. Using WbLS large-scale neutrino experiments can benefit
from both directional reconstruction and enhanced low-energy efficiency.
Furthermore, broadening the science capability of such materials by metal
doping may be better suited for water based liquid scintillators. We recently
constructed and commissioned a 1-ton WbLS detector with good photosensor
coverage and a capable data acquisition 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 analysis results.
