The Use of a Passive Scatterer for SPS Slow Extraction Beam Loss Reduction
/ Goddard, Brennan (CERN) ; Balhan, Bruno (CERN) ; Borburgh, Jan (CERN) ; Fraser, Matthew (CERN) ; Stoel, Linda (CERN) ; Velotti, Francesco (CERN)
A significant reduction in the fraction of protons lost on the SPS electrostatic septum ES during resonant slow extraction is highly desirable for present Fixed-Target beam operation, and will become mandatory for the proposed SHiP experiment, which is now being studied in the framework of CERN's Physics Beyond Colliders program. In this paper the possible use of a passive scattering device (diffuser) is investigated. [...]

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.

DESIGN AND CONSTRUCTION OF THE CERN SPS EXTRACTION PROTECTION ELEMENTS FOR LIU
Reference: Poster-2019-689
Created: 2019. -1 p
Creator(s): Balhan, Bruno
At CERN, the SPS synchrotron is equipped with two fast extraction channels towards the LHC. As a part of the LHC injector upgrade project (LIU), the protection devic- es upstream of the septa in both extraction channels will be upgraded. Various failure scenarios have been studied and presented in the past, but the definitive approach for the equipment protection upgrade for each channel has now been determined. This paper describes the consequences of the most significant failure scenarios and the impact of the heat deposition in the diluter. The resulting material stresses are evaluated. The detailed layout for the extraction protection equipment for each extraction channel is outlined. The final layout consists of a extended diluter in Long Straight Section (LSS) 6 (TPSG6) and the installation of an additional mov- able absorber (TPSC4) upstream of the quadrupole in front of the existing protection equipment in LSS 4. The detailed mechanical design of the TPSC4 and the construction status of both TPSC4 and TPSG6 are discussed.

The LHC injection regions accommodate a system of beam-intercepting devices which protect superconducting magnets and other accelerator components in case of mis-steered injected beam or accidentally kicked stored beam, e.g. due to injection kicker or timing malfunctions. [...]
