A new proton synchrotron, the PS2, was proposed to replace the current proton synchrotron at CERN for the LHC injector upgrade. Nonlinear space charge effects could cause significant beam emittance growth and particle losses and limit the performance of the PS2. In this paper, we report on simulation studies of the potential space-charge effects at the PS2 using three-dimensional self-consistent macro-particle tracking. We will discuss the impact of space-charge effects on the beam emittance growth, especially due to synchro-betatron coupling, aperture sizes, initial painted distribution, and RF ramping schemes. The computational model used in the simulation will also be discussed.
