Since 1978, Linac2 produces beams of 50 MeV protons with a current around 160 mA, which are injected into the CERN Proton Synchrotron Booster (PSB) with conventional multi-turn injection using a horizontal septum. It is planned to replace Linac2 during a future long stop with a new H⁻ linac, Linac4, injecting at higher energy (160 MeV) and making use of the modern charge-exchange injection principle. Due to the age of Linac2 and to a delicate vacuum situation the risk of a serious Linac2 breakdown has to be considered. Therefore it is necessary to study if the PSB could produce beams useful for the LHC and other experiments injecting a Linac4 proton beam at 50 MeV with much lower average current compared to Linac2 and without the need for a long installation of the 160 MeV H⁻ injection hardware. Benchmarking of the PSB injection model with the existing injection system with Linac2 using the ORBIT code has been done for a LHC-type beam and then the injection model was used to estimate the brightness for LHC-type beams that could potentially be reached in one PSB ring with the injection of a Linac4 proton beam at 50 MeV.

Horizontal Dispersion Studies for the CERN Proton Synchrotron Booster Rings

In order to confirm the value of horizontal dispersion of the CERN Proton Synchrotron Booster (PSB) given by the MADX model, the horizontal dispersion has been measured using pick-ups and wire scanners on its four rings. The dispersion value of the PSB rings is of interest for example as input for the emittance measurements critical for high-brightness beam production for the LHC, for future optics studies related to the planned upgrades of the PSB or for optics studies of the ejection lines. In this study, the dispersion measurement protocol and the analysis of the measurements are presented. The measurement results point out differences with respect to the MADX model and also differences between the four rings. It was then investigated using the CERN survey database and MADX tracking modules whether misalignments of quadrupole magnets could explain these differences
