	Funding: This project has received funding from the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement no (PITN-GA-2011-289485-OPAC). Prior to the Long Shutdown of 2013-2014 (LS1), control of the closed orbit in the four rings of the CERN PS Booster (PSB) was achieved by adjusting the alignment of several focusing quadrupoles. After a set of orbit corrector dipoles was installed, a major realignment campaign was undertaken to remove these intentional quadrupole offsets and any other magnet misalignments. This paper summarizes the effects of the magnet realignment on the closed orbit in the PSB and the results of closed orbit correction with corrector dipoles.

	The present 50-MeV proton injection into the PS Booster will be replaced by a H⁻ charge exchange injection at 160 MeV to be provided by Linac 4. The higher energy will allow producing beams at higher brightness. A set of kicker magnets (KSW) will move the beam across the stripping foil to perform phase space painting in the horizontal plane to reduce space charge effects. The PSB must satisfy the different users with very different beams in terms of emittance and intensity. Therefore, the KSW waveforms must be adapted for each case to meet the beam characteristics while minimizing beam losses. Here we present the results of the simulations performed to optimise the injection system. A detailed analysis of the different painting schemes is discussed, including the effect of the working point on the painted beam, and variations in the offset of the injected beam.
