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. [...]

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. [...]

Operational experience of a low beam coupling impedance injection kicker magnet for the CERN SPS ring / Barnes, M J (CERN) ; Bartmann, W (CERN) ; Díaz, M (CERN) ; Ducimetière, L (CERN) ; Favia, G (CERN) ; Feliciano, L (CERN) ; Kramer, T (CERN) ; Namora, V (CERN) ; Standen, D (CERN) ; Stadlbauer, T (CERN) et al.
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. [...]

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. [...]

Fortune Telling or Physics Prediction? Deep Learning for On-Line Kicker Temperature Forecasting / Velotti, Francesco (CERN) ; Barnes, Michael (CERN) ; Goddard, Brennan (CERN) ; Revuelta, Irene (CERN)
The injection kicker system MKP of the Super Proton Synchrotron SPS at CERN is composed of 4 kicker tanks. The MKP-L tank provides additional kick needed to inject 26 GeV Large Hadron Collider LHC 25 ns type beams. [...]

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. [...]

Beam Induced Power Deposition in CERN SPS Injection Kickers / Barnes, Michael J (CERN) ; Bjorkqvist, Oskar (CERN) ; Kodama, Kota (CERN ; KEK, Tsukuba)
The SPS injection kicker magnets (MKP) were developed in the 1970’s, before beam power deposition was considered an issue and before any advanced tools for analysing beam coupling impedance were available in their current form. These magnets are very lossy from a beam impedance perspective, and the beam induced power deposition is highly non-uniform. [...]
