With the FHC Zoffset is 948 cm. Pion+, pion- , neutron and anti-neutron are shot to the center of FHC, and the positions on the surface of FHC are (124,5,948), (124,-5,948). The energy of particles are 60 GeV and I digitized

 the energy for one count is 50 Mev.

    the geometry of the FHC and FMS is
