MI-12 BNB Target Hall

The MI-12 building is the target hall for the Booster Neutrino Beam. It served for the MiniBooNE experiment, and is currently operating for the MicroBooNE experiment (LAr TPC detector).
The Booster accelerates protons to 8 GeV, and then sends the protons down the neutrino beamline. The protons hit a beryllium target situated inside a magnetic focusing horn. The mesons are produced. Positively charged mesons are focused, pass through a collimator, and then enter a 50 m long decay volume where they decay to neutrinos or absobed by the beam absorber at the end of the decay volume.

TSD is currently working on the BNB target station upgrades for the Short-Baseline Neutrino (SBN) program (SBND/ICARUS detectors). It includes a new longer horn capable of running at higher rate and current.
