Beam Transfer at CERN’s Accelerator Complex - Septa magnets for injection and extraction, state-of-the-art and future plans
Abstract: CERN’s Accelerator Beam Transfer group is in charge of the design, development, construction, installation, exploitation and maintenance of injection and extraction related equipment and beam-transfer systems. As part of the ABT group, the Septa section is responsible for electric field deflectors, electric and magnetic septa, as well as beam protection elements, used throughout CERN’s accelerator complex. Apart from regular machine operation, the Septa section also performs R&D on novel magnetic and electrostatic topologies for present and future accelerators.

Concept and development of the Superconducting Shield (SuShi) septum for the FCC
Abstract: The septum magnet is an essential part of a circular accelerator, its purpose is to safely extract the circulating beam, by increasing the distance between the extracted and circulating beamline. In order to limit the length and power losses of the extraction septum magnet of the Future Circular Collider, superconducting solutions are required. The Superconducting Shield (SuShi) septum is offering small (20 mm) apparent septum thickness for 3 Tesla field. It is foreseen to be utilized in combination with the truncated cosine theta septum with 4 Tesla field and 30 mm wall thickness. The SuShi septum creates a field-free region inside a superconducting magnet using a passive superconducting shield.
A demonstrator prototype is being developed in the collaboration of CERN, the Future Circular Collider Study, Wigner Research Centre for Physics (Budapest), and the University of Miskolc (Hungary). The presentation will overview all aspects of the SuShi septum project: the concept, proof of concept tests and performance of different shield materials, optimization and design of the magnet and the shield as well as future plans for the testing of the magnet.
