Low impedance design with example of kickers (including cables) and potential of metamaterials / Zannini, C (CERN) ; Barnes, M.J. (CERN) ; Biancacci, N (CERN) ; Danisi, A (CERN) ; Koukovini-Platia, E (CERN) ; Métral, E (CERN) ; Rumolo, G (CERN) ; Salvant, B (CERN)
Unmatched terminations of single elements were recently identified to be responsible for beam instabilities in the CERN PSB and LEIR machines. Impedance models are needed to estimate the impedance of similar devices and to assess potential intensity limitations. [...]

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. [...]

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. [...]

Electron Cloud observation in the LHC / Rumolo, G (CERN) ; Arduini, G (CERN) ; Baglin, V (CERN) ; Bartosik, H (CERN) ; Biancacci, N (CERN) ; Baudrenghien, P (CERN) ; Bregliozzi, G (CERN) ; Chiggiato, P ; Claudet, S (CERN) ; De Maria, R (CERN) et al.
Operation of LHC with bunch trains at different spacings has revealed the formation of an electron cloud inside the machine. The main observations of electron cloud build up are the pressure rise measured at the vacuum gauges in the warm regions, as well as the increase of the beam screen temperature in the cold regions due to an additional heat load.

Building the impedance model of a real machine / Salvant, Benoit (CERN) ; Amorim, David (CERN ; Grenoble, INP) ; Antipov, Sergey (CERN) ; Arsenyev, Sergey (CERN) ; Beck, Mario (CERN) ; Biancacci, Nicolo (CERN) ; Brüning, Oliver (CERN) ; Campelo, Jose Enrique (CERN) ; Carideo, Emanuela (CERN) ; Caspers, Fritz (CERN) et al.
A reliable impedance model of a particle accelerator can be built by combining the beam coupling impedances of all the components. This is a necessary step to be able to evaluate the machine performance limitations, identify the main contributors in case an impedance reduction is required, and study the interaction with other mechanisms such as optics nonlinearities, transverse damper, noise, space charge, electron cloud, beam-beam (in a collider).

Detailed Electromagnetic Characterisation of HL-LHC Low Impedance Collimators / Kurtulus, Adnan (CERN ; ETH, Zurich (main)) ; Accentura, Carlotta (CERN) ; Biancacci, Nicolo (CERN) ; Carra, Federico (CERN) ; Caspers, Fritz (CERN) ; Chitnis, Ninad (CERN) ; Giordano, Francesco (CERN) ; Illan Fiastre, Ricardo (CERN) ; Joly, Sébastien (CERN) ; Lamas Garcia, Inigo (CERN) et al.
The High Luminosity Large Hadron Collider (HL-LHC) project will upgrade the LHC machine to allow operation with increased luminosity for the experiments. In order to achieve this goal, different operational parameters of the machine need to be pushed beyond the present design values, including the stored beam energy. [...]

High frequency electromagnetic characterization of NEG properties for the CLIC damping rings / Koukovini-Platia, E (CERN) ; Rumolo, G (CERN) ; Zannini, C (CERN)
Coating materials will be used in the CLIC damping rings (DR) to suppress two-stream effects. In particular, NEG coating is necessary to suppress fast beam ion instabilities in the electron damping ring (EDR). [...]

Electromagnetic Characterization of Materials for the CLIC Damping Rings   / Koukovini-Platia, E (EPFL Lausanne ; CERN) ; De Michele, G (EPFL Lausanne ; PSI, Switzerland) ; Zannini, C (CERN) ; Rumolo, G (CERN)
WP: 4: AccNet: Accelerator Science Networks
Task: 4.3: RFTech

The performance of the Compact LinearCollider (CLIC) damping rings (DR) is likely to be limited by collective effects due to the unprecedented brilliance of the beams. [...]
