Impedance reduction of the beam gas ionization monitors for the CERN SPS / Bursali, Hikmet (CERN) ; Andreazza, William (CERN) ; Khatri, Ghanshyambhai (CERN) ; Ramos Garcia, Maria Teresa (CERN) ; Storey, James (CERN) ; Vollenberg, Wil (CERN) ; Vollinger, Christine (CERN)
The beam gas ionization monitors (BGIs) are non-destructive instruments to measure the transverse beam profiles. With the goal to double the beam intensity in the injector chain for the High-Luminosity Large Hadron Collider (HL-LHC), any element contributing to the overall beam coupling impedance requires an in-depth impedance evaluation from the design stage. [...]

Evaluation of Longitudinal Beam Impedance in the Beam Gas Ionization Monitor of the CERN-PS Accelerator / Nasr Esfahani, Nasrin (CERN) ; Kaltenbacher, Thomas (CERN) ; Storey, James (CERN) ; Vollinger, Christine (CERN)
The recently observed beam induced heating issues in the BGI monitors of the LHC which could have been occurred due to a strong coupling between the beam and the localized modes at the sensor location showed the general importance of a thorough evaluation of the beam coupling impedance and the corresponding heat deposit in beam monitoring equipments. This paper is devoted to the examination of the beam coupling impedance and beam induced heating for a currently under development beam gas ionization (BGI) monitor which is intended to be a part of the CERN Proton Synchrotron (PS) beam monitoring equipment.

Needs and Solutions for Machine Impedance Reduction / Vollinger, C (CERN) ; Farricker, A (CERN) ; Kaltenbacher, T R (CERN) ; Kramer, P (CERN) ; Popovic, B K (CERN)
Particle beams with highest possible beam intensities are requested nowadays, hence in modern circular accelerators, the consideration of beam coupling impedance issues is of increasing relevance. Classical sources of beam coupling impedance are RF-systems, injection and extraction kickers, but also beam diagnostic elements such as wire scanners where the object itself forms an undesired cavity, and beam pipe transitions, namely tapers or steps.

Characterization of Shielding for the CERN-SPS Vacuum Flanges With Respect to Beam Coupling Impedance / Kaltenbacher, Thomas (CERN) ; Vollinger, Christine (CERN)
Longitudinal multi-bunch instabilities in the CERN-SPS pose a serious limitation for future beam intensities required for high luminosity LHC. Hence, an impedance model for the SPS accelerator was developed from which one group of vacuum flanges could be identified as being a major culprit for these instabilities. [...]
