Description

The third-integer resonant extraction of the proton beam from the Super Proton Synchrotron (SPS) at CERN is a technique used for slow extraction of the circulating beam, providing a constant spill of protons to the North Area experiments.
Currently, this method deploys an electrostatic septum (ZS) to separate the extracted particles from the proton beam circulating in the ring. However a fraction of the protons is lost on the mechanical parts of the ZS causing its activation and, thus, limiting the efficiency of the process.
In this work, the first considerations for solving this problem are presented with the goal of replacing the ZS with new bent crystals.
The extraction efficiency and beam quality are benchmarked using the Xsuite particle tracking framework for a new configuration, which is compared with the present setup.
