Mismatch between the PSB and CPS due to the present vertical recombination scheme

The production of the nominal LHC beam will demand optimum emittance preserva­ tion between individual machines in the injection chain. The edge effects at the entry and exit of the bending magnets used for the vertical recombination of the four PS booster rings to the level of the CPS results in a small un-compensated, and for each ring, different mismatch. We are here presenting recent measurements of the mismatch done in the PSB measurement line.
