Pion and muon yields from a 10 GeV proton beam on various targets
  We present results from MARS Monte Carlo simulations of the accepted pion and muon yields when a 10 GeV parabolic proton beam interacts with a solid or powdered (50% density) tungsten target for a Neutrino Factory. We compare these yields with the mercury jet target configuration and find that they all give similar rates of pion production. Also provided are estimates of the amount of pion re-absorption inside the target.
