Samples:
- epAthena, Athena geometry, simulation VMC+gcalor (ROOT5 VMC geometry + gcalor),, with magnetic field from EIC_v.2.0.3_Magnetic_Field_Map_2021_09_28_radial_coords_cm_T.Bmap.txt, the ep kinematics from pythia.ep.18x275.1Mevents.RadCor=0.Q2=0.00001-1.0.kT=1, and the primary vertex σZ = 11 cm.
The are a few short comings:
- ROOT5 VMC does not recognized some TGeo classes ( TGDMLMatrix, TGeoOpticalSurface, TGeoSkinSurface), which I am assume is coming from ROOT6.
- There are unrecognized particles (wrong pdg) in pythia.ep.*.root files.
- pp2017_510GeVB, pythia, pythia pp510 GeV, STAR geometry 2017, GEANT3+GCALOR simulation (the same simulation as published in Yuri Fisyak et al., "Thermal neutron flux measurements in the STAR experimental hall", Nucl.Instrum.Meth. A756 (2014) 68-72, DOI: 10.1016/j.nima.2014.04.035).
- pp2017_510GeV_gcalorC, pythia pp 510 GeV, STAR geometry 2017. VMC+gcalor (ussing TGeo geometry with TGeant3 and gcalor)
- ppp510_AtheangcalorB, pythiaa pp 510 GeV, Athena geometry, STAR magnetic field. Just for cross check.
Legend
- The plots are normalized on 1 MHz minimum biased collision rate.
- All plots have an associated root files with canvas and can be downloaded by clicking on picture. The canvas can be redrawn in root and any number can be obtained from the canvas via Options → Status Bar.
