MINER$\nu$A Experiment Magnetic Spectrometer Characterization and Simulation

MINER$\nu$A experiment (http://minerva.fnal.gov) is a high statistics scattering neutrino experiment, installed 105 meters down the Fermilab NuMI line. For calibration it was planned, constructed and commissioned a test beam line experiment, consisted of a target, a collimator, a time of flight system, four multiwire chambers, two identical dipole magnets, and a test beam detector. The entire test beam line was simulated. Here we present details and results of the dipole magnets simulations, which are in excellent agreement with measurements.
