/ Favia, Giorgia (CERN) ; Zannini, Carlo (CERN) ; Standen, Dylan (CERN) ; Velotti, Francesco (CERN) ; Ducimetière, Laurent (CERN) ; Feliciano, Luis (CERN) ; Barnes, Michael (CERN) ; Diaz Zumel, Miguel (CERN) ; Trubacova, Pavlina (CERN) ; Kramer, Thomas (CERN) et al.
The SPS injection kicker system comprises twelve MKP-S (small aperture) modules and four MKP-L (large aperture) modules. An upgraded MKP-L magnet was installed in the SPS, during December 2022, in view of the higher beam intensity needed in the future for High-Luminosity-LHC. [...]

Initial operational experience of an LHC injection kicker magnet upgraded for HL-LHC
/ Barnes, Michael (CERN) ; Diaz Zumel, Miguel (CERN) ; Bracco, Chiara (CERN) ; Standen, Dylan (CERN) ; Favia, Giorgia (CERN) ; Ducimetière, Laurent (CERN) ; Trubacova, Pavlina (CERN) ; Kramer, Thomas (CERN) ; Stadlbauer, Tobias (CERN) ; Gomes Namora, Vasco (CERN)
The intensity of the HL-LHC beam will be twice that of LHC. Hence, an upgrade of the LHC injection kickers (MKIs) is necessary for HL-LHC to avoid excessive beam induced heating of the MKIs. [...]

Production and validation of the RF cooling damper for the LHC injection kickers
/ Trubacova, Pavlina (CERN) ; Gerardin, Alexandre (CERN) ; Favia, Giorgia (CERN) ; Geisser, Jean-Marie (CERN) ; Scibor, Karol (CERN) ; Ducimetière, Laurent (CERN) ; Barnes, Michael (CERN) ; Diaz Zumel, Miguel (CERN) ; Kramer, Thomas (CERN)
Fast single-turn injection kicker systems deflect incoming beam onto the orbit of the LHC. The higher intensities of High Luminosity (HL) LHC beams are predicted to cause the ferrite yokes of the LHC injection kicker magnets (MKI), in their current configuration, to heat up to their Curie temperature. [...]

Chapter 19: Injection and Beam Dump Systems

Some of the elements of the LHC injection and extraction systems will be upgraded or replaced to adapt to the increased beam brightness and intensity of the HL-LHC beams [1; 2]. The injection main protection absorber will be replaced with new hardware which will be able to absorb and withstand 288 HL-LHC bunches in case of an injection kicker failure. [...]

MKP-L Impedance Mitigation and Expectations for MKP-S in the CERN-SPS

Beam coupling impedance mitigation is key in preventing intensity limitations due to beam stability issues, heating and sparking. In this framework, a very good example is the optimization of the SPS kickers beam-coupling impedance for beam-induced heating mitigation. [...]

New pulse forming line and transmission cables for the CERN PS booster extraction and transfer kickers
/ Kramer, Thomas (CERN) ; del Barrio Montañés, Alicia (CERN) ; Ducimetière, Laurent (CERN) ; Trubacova, Pavlina (CERN) ; Stadlbauer, Tobias (CERN)
The CERN PS booster features four extraction kicker systems, one for each of the four superposed rings and three transfer kicker systems for recombination of the beams when being transferred towards the PS. Each of these systems consist of SF6 gas filled Pulse Forming Lines (PFL) which are resonantly charged and then fast discharged by thyratron switches into SF6 gas filled transmission cables, transferring the pulse to the magnets.

Operational experience of a low beam coupling impedance injection kicker magnet for the CERN SPS ring

The CERN SPS injection kicker magnets (MKP) were developed in the 1970's, before beam power deposition was considered an issue. There are two types of these magnets in the SPS: MKP-S (small aperture) and MKP-L (large aperture) versions. [...]

Design of a new CERN SPS injection system via numerical optimisation

The Super Proton Synchrotron (SPS) injection system plays a fundamental role to preserve the quality of injected high-brightness beams for the Large Hadron Collider (LHC) physics program and to maintain the maximum storable intensity. The present system is the result of years of upgrades and patches of a system not conceived for such intensities and beam qualities. [...]

Beam-induced heating mitigation of the SPS kickers: a crucial upgrade to move towards HL-LHC beam intensities
/ Zannini, C (CERN) ; Barnes, M (CERN) ; Diaz, M (CERN) ; Ducimetière, L (CERN) ; Standen, D (CERN) ; Rumolo, G (CERN) ; Trubacova, P (CERN)
Beam-induced heating of equipment can have several undesirable effects, including rendering the equipment temporarily inoperative, equipment degradation and/or damage. Hence, to avoid these problems, it can be necessary to limit beam intensity. [...]
