Impact of Vibration to HL-LHC Performance During the FPF Facility Construction / Gamba, Davide (CERN) ; Bartosik, Hannes (CERN) ; Guinchard, Michael (CERN) ; Osborne, John Andrew (CERN) ; Balazs, Kincso (CERN) ; Vendeuvre, Camille (CERN) ; Wenninger, Jorg (CERN) ; Widuch, Kacper (CERN)
The Forward Physics Facility (FPF) is a proposed experimental site intended to be positioned several hundred meters downstream from the ATLAS interaction point. It aims to capture long- lived particles and neutrinos that travel along the beam collision axis and fall outside the ATLAS detector’s range. [...]

Beam loss studies for the P42 beamline at the CERN SPS North Area / Dyks, Luke Aidan (University of Oxford (GB)) ; Ahdida, Claudia (CERN) ; Banerjee, Dipanwita (CERN) ; Baratto Roldan, Anna (CERN) ; Bernhard, Johannes (CERN) ; Brugger, Markus (CERN) ; Charitonidis, Nikolaos (CERN) ; Fraser, Matthew Alexander (CERN) ; Gatignon, Lau (Lancaster University (GB)) ; Goillot, Alice Marie (CERN) et al.
The P42 beamline transports 400 GeV protons from the CERN SPS between the T4 and T10 targets. A secondary particle beam is produced at the T10 target and transported along the K12 beamline to the experimental cavern ECN3, presently housing the NA62 experiment. [...]

Characterisation of the optics of the TT24 and P42 beamlines in the CERN SPS North Area / Dyks, Luke Aidan (University of Oxford (GB)) ; Banerjee, Dipanwita (CERN) ; Baratto Roldan, Anna (CERN) ; Bernhard, Johannes (CERN) ; Brugger, Markus (CERN) ; Charitonidis, Nikolaos (CERN) ; Fraser, Matthew Alexander (CERN) ; Gatignon, Lau (Lancaster University (GB)) ; Goillot, Alice Marie (CERN) ; Gorn, Aleksandr (CERN) et al.
400 GeV protons extracted from the CERN SPS are transported to the T4 target via the TT20 transfer line. The P42 beamline then transports the protons that did not interact in the T4 target to the T10 target. [...]

A high-harmonic RF system that could serve multiple purposes was proposed for the LHC. Possible applications of the second harmonic RF system include beam stabilisation in the longitudinal plane in the absence of wide-band longitudinal feedback and reduction of bunch peak line-density. [...]

Characterisation of Cherenkov Diffraction Radiation Using Electro-Optical Methods / Schlögelhofer, Andreas (CERN ; TU Vienna) ; Duvillaret, Lionel (KAPTEOS) ; Lefèvre, Thibaut (CERN) ; Mazzoni, Stefano (CERN) ; Senes, Eugenio (CERN)
The properties of Cherenkov diffraction radiation (ChDR) have been studied extensively during the recent years to be exploited for non-invasive beam diagnostic devices for short bunches. The dependence of charge and the influence of the bunch form factor on the coherent part of the radiated spectrum have been demonstrated and studied in the past. [...]

Bunch-by-bunch Tune Shift Studies for LHC-type Beams in the CERN SPS / Mases Solé, Ingrid (CERN ; Goethe U., Frankfurt (main)) ; Bartosik, Hannes (CERN) ; Paraschou, Konstantinos (CERN) ; Schenk, Michael (CERN) ; Zannini, Carlo (CERN)
After the implementation of major upgrades as part of the LHC Injector Upgrade Project (LIU), the Super Proton Synchrotron (SPS) delivers high intensity bunch trains with 25 ns bunch spacing to the Large Hadron Collider (LHC). These beams are exposed to several collective effects in the SPS, such as beam coupling impedance, space charge and electron cloud, leading to relatively large bunch-by-bunch coherent and incoherent tune shifts. [...]

Probing Transverse Impedances in the High Frequency Range at the CERN SPS / de la Fuente, Elena (CERN ; Tech. U. Madrid (main)) ; Bartosik, Hannes (CERN) ; Mases Solé, Ingrid (CERN ; Goethe U., Frankfurt (main)) ; Rumolo, Giovanni (CERN) ; Zannini, Carlo (CERN)
The SPS transverse impedance model, which includes the major impedance contributions in the machine, can be benchmarked through measurements of the Head-Tail mode zero instability. Since the SPS works above transition energy, the head tail mode zero is unstable for negative values of chromaticity. [...]

Electron Cloud Effects in the CERN Accelerators in Run 3 / Mether, Lotta (CERN) ; Bartosik, Hannes (CERN) ; Giacomel, Lorenzo (CERN) ; Iadarola, Giovanni (CERN) ; Johannesson, Sofia (CERN) ; Mases Solé, Ingrid (CERN) ; Paraschou, Konstantinos (CERN) ; Rumolo, Giovanni (CERN) ; Sabato, Luca (CERN) ; Zannini, Carlo (CERN) et al.
Several of the machines in the CERN accelerator complex, in particular the Large Hadron Collider (LHC) and the Super Proton Synchrotron (SPS), are prone to the build-up of electron clouds. Electron cloud effects are observed especially when the machines are operated with a 25 ns bunch spacing, which has routinely been used in the LHC since the start of its second operational run in 2015.

The AWAKE experiment is to be constructed at the CERN Neutrinos to Gran Sasso facility (CNGS). This will be the first experiment to demonstrate electron acceleration by use of a proton driven plasma wakefield. [...]

Revised Collimation Configuration for the Updated FCC-hh Layout / Abramov, Andrey (CERN) ; Bruce, Roderik (CERN) ; Giovannozzi, Massimo (CERN) ; Pérez Segurana, Gustavo (CERN) ; Redaelli, Stefano (CERN) ; Risselada, Thys (CERN)
The collimation system for the hadron Future Circular Collider (FCC-hh) must handle proton beams with an unprecedented nominal beam energy and stored beam energy in excess of 8 GJ, and protect the superconducting magnets and other sensitive equipment while ensuring a high operational efficiency. The recent development of the 16-dipole lattice baseline for the FCC-hh, and the associated layout changes, has necessitated an adaptation of the collimation system. [...]
