Abstract：
Uranium on uranium target (U+U) collision experiment has been proposed to be performed on Cooling Storage Ring (CSR), External Target Facility (ETF), which is to be built at Lanzhou, China, delivering the uranium beam up to 520 MeV/nucleon. It is predicted that the tip-tip U+U collision patterns can produce significant high baryon density and long duration nuclear matter to study the nuclear Equation of State (EoS). As the random orientation in U+U collisions, it is necessary to select the interested tip-tip events from the large trivia background. A Relativistic Transport (ART1.0) Model is applied to compute the random mini-biased U+U collisions to select our most favorable tip-tip events. It is found that applying various combination cut on the forward neutron multiplicity and forward charged particle multiplicity of the random U+U mini-biased sample, we can select the tip-tip configuration with certain purity and efficiency.
