Measurements of Electromagnetic Properties of Ferrites as a Function of Frequency and Temperature / Chmielinska, Agnieszka (CERN ; Ecole Polytechnique, Lausanne) ; Barnes, Michael (CERN) ; Caspers, Fritz (CERN) ; Popovic, Branko (CERN) ; Vollinger, Christine (CERN)
Fast kicker magnets are used to inject beam into and extract beam out of the CERN accelerator rings. These kickers are often ferrite loaded transmission line type magnets with a rectangular shaped aperture through which the beam passes. [...]

Impact of a Wideband Feedback Prototype System on TMCI in the SPS / Höfle, Wolfgang (CERN) ; Bartosik, Hannes (CERN) ; Bjørsvik, Endre (CERN) ; Dusatko, John (SLAC) ; Fox, John (SLAC) ; Kotzian, Gerd (CERN) ; Levens, Thomas (CERN) ; Li, Kevin (CERN) ; Rivetta, Claudio (SLAC) ; Turgut, Ozhan (Stanford U.)
The transverse mode coupling instability (TMCI) in the SPS has been identified as one of the potential performance limitations for future high intensity LHC beams that will be required for the High Luminosity (HL)-LHC era and is being addressed by the LHC Injector Upgrade Project (LIU). A potential mitigation can be provided by wideband feedback systems with a frequency reach of about 1 GHz . [...]

Control of Intra-Bunch Vertical Motion in the SPS with GHz Bandwidth Feedback / Fox, John (SLAC) ; Bartosik, Hannes (CERN) ; Bjørsvik, Endre (CERN) ; De Santis, Stefano (LBNL, Berkeley) ; Dusatko, John (SLAC) ; Höfle, Wolfgang (CERN) ; Kotzian, Gerd (CERN) ; Li, Kevin (CERN) ; Métral, Elias (CERN) ; Rivetta, Claudio (SLAC) et al.
A GHz bandwidth vertical beam feedback system has been in development at the CERN SPS for control of unstable vertical beam motion in single bunch and bunch train configurations. We present measurements and recent studies of stable and unstable motion for intensities up to 2 × 1011 p/bunch[1]. [...]

Transverse Feedback System for the CERN FCC-hh Collider / Höfle, Wolfgang (CERN) ; Komppula, Jani (CERN) ; Kotzian, Gerd (CERN) ; Li, Kevin (CERN) ; Valuch, Daniel (CERN)
For the future hadron Collider (FCC-hh) being studied at CERN a strong transverse feedback system is required to damp coupled bunch instabilities. This system is also planned to be used for injection damping. [...]

Improvement of the Longitudinal Beam Transfer from PS to SPS at CERN / Lasheen, Alexandre (CERN) ; Damerau, Heiko (CERN) ; Repond, Joël (CERN) ; Schwarz, Markus (CERN) ; Shaposhnikova, Elena (CERN)
The beam transfer from the Proton Synchrotron (PS) to the Super Proton Synchrotron (SPS) at CERN is a critical process for the production of beams for the Large Hadron Collider (LHC). A bunch-to-bucket transfer is performed with the main drawback that the rf frequency in the SPS (200 MHz) is five times higher than the one in the PS (40 MHz). [...]

Uncontrolled Longitudinal Emittance Blow-Up during RF Manipulations in the CERN PS / Lasheen, Alexandre (CERN) ; Damerau, Heiko (CERN) ; Favia, Giorgia (CERN)
The CERN Proton Synchrotron (PS) determines the basic bunch spacing for the Large Hadron Collider (LHC) by means of rf manipulations. Several rf systems in a frequency range from 2.8 MHz to 200 MHz are available for beam acceleration and manipulations. [...]

Lower-Harmonic RF System in the CERN SPS / Repond, Joël (CERN) ; Damerau, Heiko (CERN) ; Lasheen, Alexandre (CERN) ; Shaposhnikova, Elena (CERN)
Significant beam losses increasing with intensity are observed at capture and along the SPS flat bottom for the LHC-type proton beam. The intensity should be doubled for HL-LHC and high losses may be a major performance limitation. [...]

In order to achieve the highest beam intensities possible in the LHC the highest quality beam possible has to be supplied by the injector chain. The Super Proton Synchrotron (SPS) at CERN is the last accelerator in the injector chain of the LHC. [...]
