Target System efficiently converts the intense proton beam into a focused neutrino beam or muon beam aimed at the detectors. TSD maintains the operation of high-intensity target system facilities, currently NuMI, BNB, and Muon g-2.
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.
The production target station consists of five main devices: the pion production target, the lithium lens, a collimator, a pulsed magnet, and a beam dump.
