Abstract

Measurements of neutrino cross-section and oscillations depend heavily on neutrino flux predictions. Such predictions rely on hadron-nucleus interaction cross-section data, and yet the data are scarce. The E907 Main Injector Particle Production (MIPP) experiment at Fermilab is a full acceptance spectrometer with excellent particle identification capabilities. MIPP has collected ∼15 x 106 events of p's, π's and K's at various momenta (from 5 to 120 GeV) on several targets spanning the periodic table, from hydrogen to uranium including beryllium and carbon. In particular, MIPP has collected hadron production data on a spare NuMI target using 120 GeV/c protons from the Main Injector. We review the experiment, performance of the spectrometer and show preliminary results of particle production for thin and thick carbon targets.
