Comparison of Superconducting Septa Topologies and Parameter Space Exploration
/ Atanasov, Miroslav (CERN) ; Borburgh, Jan (CERN) ; Hourican, Michael (CERN) ; Sanz Ull, Alejandro (CERN ; Eindhoven, Tech. U.)
The unprecedented energy scale of the FCC poses challenging requirements for its magnetic elements including the septum magnets for injection and extraction. With an ambitious target field of 4 T and an apparent septum thickness of only 25 mm, different superconducting septa topologies have been investigated to explore their limitations. [...]

Transverse beam splitting made operational: Recent progress of the multi-turn extraction at the CERN proton synchrotron
/ Huschauer, Alexander (CERN) ; Borburgh, Jan (CERN) ; Damjanovic, Sanja (CERN) ; Gilardoni, Simone (CERN) ; Giovannozzi, Massimo (CERN) ; Hourican, Michael (CERN) ; Kahle, Karsten (CERN) ; Michels, Olivier (CERN) ; Sterbini, Guido (CERN) ; Hernalsteens, Cedric (CERN ; IBA, Louvain-la-Neuve) et al.
Following a successful commissioning period, the Multi-Turn Extraction (MTE) at the CERN Proton Synchrotron (PS) has been applied for the fixed-target physics programme at the Super Proton Synchrotron (SPS) since September 2015. This exceptional extraction technique was proposed to replace the long-serving Continuous Transfer (CT) extraction, which has the drawback of inducing high activation in the ring. [...]

Direct Drive and Eddy Current Septa Magnet Designs for CERN’s PSB Extraction at 2 GeV
Reference: Poster-2015-507
Keywords: direct drive eddy current septum PSB PS
Created: 2015. -5 p
Creator(s): Szoke, Zsolt; Atanasov, Miroslav Georgiev; Balhan, Bruno; Baud, Cedric; Borburgh, Jan [...]
In the framework of the LIU project, new septa magnets have been designed between CERN’s PS Booster (PSB) extraction and PS injection. The upgraded devices are to deal with the increased beam energy from 1.4 GeV to 2 GeV at extraction of the PSB. The direct drive recombination septa in the PSB transfer line to the PS, the eddy current PS injection septum together with a bumper at injection have been investigated using finite element software. For the recombination magnets an increase in magnet length is sufficient to obtain the required deflection; however, for the PS injection elements a more novel solution is necessary to also achieve increased robustness to extend the expected lifetime of the pulsed device. The injection septum will share the same vacuum vessel with an injection bumper and both magnets will be located adjacent to each other. The new PS injection magnet will be the first septum operated at CERN based on eddy current technology. The magnetic modelling of the devices, the comparison of the performance of the present 1.4 GeV devices with the predictions for the upgraded 2 GeV devices as well as solutions retained to achieve the field requirements are described in this paper.

Ions for LHC : Beam Physics and Engineering Challenges
/ Maury, Stephan (CERN) ; Angoletta, Maria Elena ; Baggiolini, Vito ; Beuret, Andre ; Blas, Alfred ; Borburgh, Jan ; Braun, Hans Heinrich ; Carli, Christian ; Chanel, Michel ; Fowler, Tony et al.
The first phase of the heavy ion physics program at the LHC aims to provide lead-lead collisions at energies of 5.5 TeV per colliding nucleon pair and ion-ion luminosity of 1027 cm-2s-1. The transformation of CERN’s ion injector complex (Linac3-LEIR-PS-SPS) presents a number of beam physics and engineering challenges, which are described in this paper. [...]
