"SPECIAL PARTICLE SEMINAR: The Long-Baseline Neutrino Experiment and the CAPTAIN Program"

 

 

 

The Long-Baseline Neutrino Experiment (LBNE) is a broad scientific program being developed in the United States as an international partnership. LBNE consists of an intense neutrino beam produced at Fermi National Accelerator Laboratory (Fermilab), a highly capable set of neutrino detectors on the Fermilab campus, and a large underground liquid argon time-projection chamber (TPC) at Sanford Underground Research Facility in the state of South Dakota. LBNE will make detailed studies of neutrino oscillations including measurements of the mass hierarchy and CP violation that take advantage of the 1300 km baseline afforded by this arrangement. The large underground detector at the far site will open a new window to the search

for nucleon decay, supernova neutrinos, and interesting astrophysical phenomena.

The Cryogenic Apparatus for Precision Tests of Argon Interactions with Neutrino (CAPTAIN) program is designed to make measurements of scientific importance to longbaseline neutrino physics and physics topics that will be explored by large underground detectors – especially supernova neutrinos. The CAPTAIN detector is a liquid argon time-projection chamber

(TPC) deployed in a portable cryostat. Five tons of liquid argon are instrumented with a 2,000 channel TPC and a photon detection system.

In this talk, I describe the LBNE configuration and physics program and discuss the scientific impact of CAPTAIN on LBNE.
