Software and Layout Optimization of HIRFL-CSR External-target Experiment

Based on the CEE conceptual design and the CeeROOT software, configurations of its sub-detectors are optimized with considering foreseeable physical constrains. The final detector layout of the CEE spectrometer and its acceptances are validated through simulations of U+U collision at 500 MeV/u and pp collisions at 2.8 GeV, which demonstrates that the CEE experiment will serve as a detector with wide acceptance and multi-particle identification capabilities for studying high-energy nuclear physics topics at HIRFL-CSR energies with pp, pA and AA collisions.These are the relate data for our simulation resultes.
