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. [...]

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. [...]

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. [...]

Studies for Mitigating Flashover of CERN-LHC Dilution Kicker Magnets / Loebner, Alina M (CERN) ; Barnes, Michael J (CERN) ; Bartmann, Wolfgang (CERN) ; Bracco, Chiara (CERN) ; Ducimetière, Laurent (CERN) ; Namora, Vasco (CERN) ; Senaj, Viliam (CERN)
The LHC beam dump system is used for extracting beam from the LHC and, as such, is a safety critical system whose proper functionality must be assured. Dilution kicker magnets (MKBs) sweep the extracted beam over the cross-sectional area of a dump block as the energy density would otherwise be too high and damage the block. [...]

Machine protection aspects of high-voltage flashovers of the LHC beam dump dilution kickers / Wiesner, Christoph (CERN) ; Bartmann, Wolfgang (CERN) ; Bracco, Chiara (CERN) ; Calviani, Marco (CERN) ; Carlier, Etienne (CERN) ; Ducimetière, Laurent (CERN) ; Frankl, Matthias (CERN) ; Fraser, Matthew (CERN) ; Gilardoni, Simone (CERN) ; Goddard, Brennan (CERN) et al.
The LHC Beam Dump System is required to safely dispose of the energy of the stored beam. In order to reduce the energy density deposited in the beam dump, a dedicated dilution system is installed. [...]

Eradication of Mercury Ignitron from the 400 kA Magnetic Horn Pulse Generator for CERN Antiproton Decelerator / Namora, Vasco (CERN) ; Calviani, Marco (CERN) ; Ducimetière, Laurent (CERN) ; Faure, Patrick (CERN) ; Fernandez, Luis (CERN) ; Grawer, Gregor (CERN) ; Senaj, Viliam (CERN)
The CERN Antiproton Decelerator (AD) produces low-energy antiprotons for studies of antimatter. A 26 GeV proton beam impacts the AD production target which produces secondary particles including antiprotons. [...]

Operational Experience of the Upgraded LHC Injection Kicker Magnets / Barnes, Michael (CERN) ; Adraktas, Antonios (CERN) ; Bregliozzi, Giuseppe (CERN) ; Calatroni, Sergio (CERN) ; Day, Hugo (CERN) ; Ducimetière, Laurent (CERN) ; Goddard, Brennan (CERN) ; Gomes Namora, Vasco (CERN) ; Mertens, Volker (CERN) ; Salvant, Benoit (CERN) et al.
During Run 1 of the LHC the injection kicker magnets caused occasional operational delays due to beam induced heating with high bunch intensity and short bunch lengths. In addition, sometimes there were also sporadic issues with microscopic unidentified falling objects, vacuum activity and electrical flashover of the injection kickers. [...]
