A bare uranium beam is injected from the collector ring CR into the HESR at 740 MeV/u*. The simulation studies are now improved to include different injection schemes applying either the barrier cavity or the h = 1 cavity in the HESR. It is outlined how the new 2.5 MeV electron cooler at COSY Jülich or stochastic cooling can support the injection mechanism. The beam preparation for an internal target experiment with cooling is outlined. The acceleration of the ion beam is extended to 5 GeV/u under the mandatory condition of the available cavity voltages and the maximum magnetic field ramp rate in the HESR. The flexibility of the HESR ring lattice is utilized to avoid transition energy crossing during ramping up to 5 GeV/u and to adjust the rings’ frequency slip factor for optimal stochastic cooling. The cooling simulations include the beam-target interaction due to a hydrogen target.
