3 TeV pgun collisions, Single particles type, PARTICLE GUN generator: pgun_muon_eta45_p3tev

Single particle gun for detector studies: Events from a particle gun with single muons. One muon per event. 10000 events per file. Production vertex at (x,y,z,t)=(0,0,0,0). mu+ and mu- are alternated. Momentum is uniform between 1 GeV and 3 TeV. Uniform distribution in Phi. Uniform distribution in the Eta (pseudorapidity) range [-4.5, 4.5]. Requested by N.Calace for ATLAS ITK studies
