    CERN has recently built the Large Hadron Collider (LHC), a superconducting circular particle accelerator designed for colliding two proton beams at 7 TeV energy. In order for the LHC to achieve ultimate beam parameters, CERN has launched a long-term program for the progressive replacement or upgrade of the old chain of accelerators presently used as injectors for the LHC, the so-called LHC...

    An overview on the new PSB H- injection system is presented in this talk. The principle of longitudinal painting, consisting in energy modulation from Linac4, is introduced. Transverse painting in the horizontal plane, by means of four existing PSB kicker magnets (KSW), is described. Results of extensive and detailed beam dynamic studies allowed to precisely define the KSW generators waveforms...

    Per PS Booster ring, 4 outside vacuum magnets will be installed to provide the injection bump through the stripping foil. The first magnet is a septum and the following magnets are window frame dipoles, of which the last has to cope with the unstripped particle beam dumps. The talk will describe the constraints imposed on these injection chicane magnets and present the baseline implementation.

    The conceptual ideas for the dumping of the unstripped H0 and H- ions coming from the PSB injection region at the energy and beam parameters due to the Linac4 future connection is presented in this talk. The dump core itself covers longitudinally the second half of the BSW4 chicane magnet, close by but out of the trajectory of the circulating H+ beam. Due to dimension constraints and the...

    The linac4 beam will be injected horizontally into the PSB by means of an H- charge-exchange injection system using a graphite stripping foil to paint the beam into the required emittance. This presentation will describes the hardware requirements and constraints, the performance specifications of the stripping foil and the conceptual design of the foil exchange unit and motorisation.

    The Vacuum analysis for the PSB H- injection has been done by means of the electrical network – vacuum analogy: through this method it’s possible to design complex vacuum line, taking into account the gas loads, the conductances, the pumping speeds applied and the target pressure to reach. This presentation shows how the main gas sources have been taken into account (water degassing from inner...

    Beam instrumentation is essential for the commissioning phase of the PSB injection zone with the Linac4 beam, and for routine operation later on. The following observables are requested for that purpose: Beam profiles for steering and injection matching. The stripping efficiency is also monitored downstream the foil, in addition to the visual inspection of the foil. A fast machine protection...

    The novel H- injection of Linac4 into the PS Booster will require a complete rebuilding of the PSB injection section. The connection is presently foreseen to be ready for late 2015. 3 months must be available for installation of the new injection equipment and related machine modifications after one month of radiation cool-down, followed by 3 months of beam commissioning. The presentation...

    The overall concept for the new 160 MeV H- injection into the PSB is described. After a brief introduction to H- injection the PSB injection straight layout is shown, and the function of each of the main injection elements described. The specific feature of the H-injection into the PSB are listed.
