E906/SeaQuest MARS15 Simulation
  A series of MARS15 simulations were done to verify and guide the design of steel and concrete shielding, around the first E906-SeaQuest spectrometer magnet, and the target area immediately upstream of it. The result of the last round of simulations is summarized here. This magnet is a solid iron dipole magnet and serves as a beam dump, as well as a muon analysis magnet.   The E906-SeaQuest spectrometer is designed to measure high energy muons produced in the forward direction by interactions of the FNAL 120-GeV Main Injector proton beam, with a variety of targets.
