Description

In view of optimising the performance for the fixed-target experiments in the CERN accelerator complex, studies aimed at increasing intensity in the Proton Synchrotron (PS) are currently taking place. Measurements have revealed losses along the PS cycle for the high intensity beams destined for the nTOF facility, with the majority originating from the transition energy crossing. As well as beam intensity, the transverse beam characteristics were also identified to have an impact on the magnitude of losses, hinting to possible aperture limitations due to the optics perturbations of the transition energy crossing γτ-jump scheme. The possibility to modify the existing γτ-jump quadrupole position along the PS ring is examined, in an attempt to optimise the crossing in terms of losses and transverse parameter evolution.
