160 MeV H^- Injection from LINAC4

The ultimate luminosity (2.3 x 10³⁴ cm^-2 s^-1) in the LHC can only be reached or even exceeded if a major upgrade of the CERN proton injector complex takes place. The first identified bottleneck towards higher brightness beams is the 50 MeV proton injection of Linac2 into the PS booster (PSB). Doubling the intensity in the PSB can be achieved with a new linac (Linac4), which increases the injection energy to 160 MeV. Linac4 will provide H- ions and use charge-exchange injection into the PSB instead of using the present multi-turn injection. We present the current status of simulations with ACCSIM, ORBIT, and ESME for all three planes. We use different initial distributions, compare the results of ACCSIM and ORBIT and highlight their differences.
