SPS injection kicker system: 2023 operational experience and upgrade proposals for high-luminosity LHC / 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. [...]

Qualification of components for installation in LHC kicker magnets / Diaz Zumel, Miguel (CERN) ; Bracco, Chiara (CERN) ; Standen, Dylan (CERN) ; Favia, Giorgia (CERN) ; Ducimetière, Laurent (CERN) ; Barnes, Michael (CERN) ; Trubacova, Pavlina (CERN) ; Maurin, Theo (CERN) ; Stadlbauer, Tobias (CERN)
LHC injection kickers (MKI) are pulsed at high voltage to achieve magnetic field pulses with fast rise time. The MKIs contain a beam screen to help shield their ferrite yoke from beam induced heating. [...]

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. [...]

MKP-L Impedance Mitigation and Expectations for MKP-S in the CERN-SPS / Zannini, Carlo (CERN) ; Barnes, Michael (CERN) ; Beck, Mario (CERN) ; Díaz Zumel, Miguel (CERN) ; Ducimetière, Laurent (CERN) ; Rumolo, Giovanni (CERN) ; Standen, Dylan (CERN) ; Trubacova, Pavlina (CERN)
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.

Design of a 30kA pulsed current generator for a new eddy current septum in the CERN PS extraction. / Gräwer, Gregor (CERN) ; Ducimetière, Laurent (CERN) ; Huon, Stéphane (CERN)
The presently used direct drive septum magnet (PE.SMH16) deflects protons and ions into the extraction transfer line TT2 from PS ring SS16 towards the experimental areas of the PS complex and the SPS. [...]

Mitigation of High Voltage Breakdown of the Beam Screen of a CERN SPS Injection Kicker Magnet / Barnes, Michael (CERN) ; Bartmann, Wolfgang (CERN) ; Díaz Zumel, Miguel (CERN) ; Ducimetière, Laurent (CERN) ; Feliciano, Luis (CERN) ; Kramer, Thomas (CERN) ; Namora, Vasco (CERN) ; Stadlbauer, Tobias (CERN) ; Standen, Dylan (CERN) ; Trubacova, Pavlina (CERN) et al.
The SPS injection kicker magnets (MKP) were developed in the 1970’s, before beam induced power deposition was considered an issue. These magnets are very lossy from a beam impedance perspective: this is expected to be an issue during SPS operation with the higher intensity beams needed for HL-LHC. [...]

SPS Beam Dump System (SBDS) Commissioning After Relocation and Upgrade / Van Trappen, Pieter (CERN) ; Carlier, Etienne (CERN) ; Ducimetière, Laurent (CERN) ; Namora, Vasco (CERN) ; Senaj, Viliam (CERN) ; Velotti, Francesco (CERN) ; Voumard, Nicolas (CERN)
In order to overcome several machine limitations, the SBDS has been relocated from LSS1 (Long Straight Section 1) to LSS5 during LS2 (Long Shutdown 2) with an important upgrade of the extraction kicker installation. An additional vertical deflection kicker magnet (MKDV) was produced and installed while the high voltage (HV) pulse generators have been upgraded by changing gas-discharge switches (thyratrons and ignitrons) to semiconductor stacks operating in oil. [...]

SF6 Gas Replacement in Pulsed High Voltage Coaxial Cables / Stadlbauer, Tobias (CERN) ; Kramer, Thomas (CERN) ; Kontelis, Dimitrios (CERN) ; Ducimetière, Laurent (CERN) ; Sermeus, Luc (CERN) ; Woog, David (CERN)
Several fast pulsed high voltage kicker systems at CERN use coaxial cables with SF$_6$ gas as dielectric. Leak detection systems are installed and for interventions, the gas is recuperated and re-circulated, reducing emissions to a minimum. [...]
