摘要：
A Monte-Carlo simulation was done to study the influence of the internal pellet and carbon foil target to the beam in the CSRm without electron cooling. The results show that the beam loss is mainly due to the growth of beam emittance caused by the small angle Coulomb scattering in the target, and lifetime of the beam is proportional to the beam energy and inverse proportional to the target thickness. For 2.6 GeV proton beam, lifetime in the CSRm is about 100 s with pellet target (1 × 1016atoms·cm-2) and will drop to 1 s with carbon foil target (5 × 1017atoms·cm-2).
