Beam Dump Facility Target: Design Status and Beam Tests in 2018
/ Lopez Sola, Edmundo (CERN) ; Aberle, Oliver (CERN) ; Avigni, Pietro (CERN) ; Bianchi, Laura (CERN) ; Busom, Josep (CERN) ; Calviani, Marco (CERN) ; Casolino, Mirkoantonio (CERN) ; Espadanal, Joao (CERN) ; Fraser, Matthew (CERN) ; Girod, Sylvain (CERN) et al.
The Beam Dump Facility (BDF) Project, currently in its design phase, is a proposed general-purpose fixed target facility at CERN, dedicated to the Search for Hidden Particles (SHiP) experiment in its initial phase. At the core of the installation resides the target/dump assembly, whose aim is to fully absorb the high intensity 400 GeV/c SPS beam and produce charmed mesons. [...]

Lifetime and Beam Losses Studies of Partially Strip Ions in the SPS ($^{129}$Xe$^{39+}$)
/ Hirlaender, Simon (CERN) ; Alemany-Fernández, Reyes (CERN) ; Bartosik, Hannes (CERN) ; Biancacci, Nicolo (CERN) ; Bohl, Thomas (CERN) ; Cettour Cave, Stephane (CERN) ; Cornellis, Karel (CERN) ; Goddard, Brennan (CERN) ; Kain, Verena (CERN) ; Krasny, Mieczyslaw (Paris U., VI-VII ; Paris, IN2P3 ; CERN) et al.
The CERN multipurpose Gamma Factory proposal relies on using Partially Stripped Ion (PSI) beams, instead of electron beams, as the drivers of its light source. If such beams could be successfully stored in the LHC ring, fluxes of the order of $10^{17}$ photons/s, in the $\gamma$-ray energy domain of $1 \leq \rm{E}_{\gamma} \leq 400$ MeV could be achieved. [...]

Observed proton beam induced disruption of a tungsten powder sample at CERN
/ Davenne, T (Rutherford) ; Loveridge, P (Rutherford) ; Bingham, R (Rutherford ; Strathclyde U.) ; Wark, J (University Coll. London) ; Back, J J (Warwick U.) ; Caretta, O (Rutherford) ; Densham, C (Rutherford) ; O'Dell, J (Rutherford) ; Wilcox, D (Rutherford) ; Fitton, M (Rutherford)
Fluidized tungsten powder has been proposed as a potential target technology for particle accelerator applications with very high power highly focused pulsed beams. This has motivated a series of experiments carried out at the HiRadMat facility at CERN to study the response of a tungsten powder sample to an impinging high energy proton beam pulse. [...]

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

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]. [...]
