Update of Facility Technical Studies for the FPF / Boyd, Jamie (CERN) ; Gamba, Davide (CERN) ; Osborne, John Andrew (CERN) ; Bud, Tamara Alice (CERN) ; Balazs, Kincso (CERN) ; Corso, Jean-Pierre (CERN) ; Magazinik, Anastasiya (Tampere University of Technology (FI)) ; Navascues Cornago, Angel (CERN)
The Forward Physics Facility (FPF) has been proposed to house a set of detectors to study collider neutrinos and search for new particles in the High-Luminosity LHC era. This report provides an update to the space and infrastructure requirements of the Facility, a result of integration studies carried out by CERN technical teams in conjunction with the FPF experimental community.

Beam loss detection based on generation of Cherenkov light in optical fibers in the CERN Linear Electron Accelerator for Research / Benítez, S (CERN) ; Salvachúa, B (CERN) ; Chen, M (CERN)
Cherenkov optical beam loss monitors (oBLMs) based on optical fibers are a revolutionary achievement among the monitoring systems in particle accelerators. Due to the nature of the Cherenkov phenomenon and the intrinsic characteristics of optical fibers, the photon production and fiber light transmission need to be studied to deduce the total amount of Cherenkov photons detected by the photosensors attached at the end of the system.

Beam physics studies for a high charge and high beam quality laser-plasma accelerator / Marini, Samuel (IRFU, Saclay, DACM) ; Minenna, Damien F G (IRFU, Saclay, DACM) ; Massimo, Francesco (LPGP, Orsay) ; Batista, Laury (IRFU, Saclay, DACM) ; Bencini, Vittorio (CERN) ; Chancé, Antoine (IRFU, Saclay, DACM) ; Chauvin, Nicolas (IRFU, Saclay, DACM) ; Doebert, Steffen (CERN) ; Farmer, John (Munich, Max Planck Inst.) ; Gschwendtner, Edda (CERN) et al.
Electron acceleration by laser-plasma techniques is approaching maturity and is getting ready for the construction of particle accelerators with dedicated applications. We present a general methodology showing how beam physics studies can be used to achieve a specific parameter set in a laser-plasma accelerator. [...]

Background mitigation concepts for SUPER-NaNu / Stummer, Florian Wolfgang (University of London (GB)) ; Andersen, Emily Marie (University of Bergen (NO)) ; Banerjee, Dipanwita (CERN) ; Baratto Roldan, Anna (CERN) ; Bernhard, Johannes (CERN) ; Boogert, Stewart Takashi (University of Manchester (GB)) ; Brugger, Markus (CERN) ; Charitonidis, Nikolaos (CERN) ; Dyks, Luke Aidan (University of Oxford (GB)) ; Gatignon, Lau (Lancaster University (GB)) et al.
Super-NaNu is a proposed neutrino experiment as part of the SHADOWS proposal for the high intensity facility ECN3 in CERN’s North Area. It aims to detect neutrino interactions downstream of a beam-dump that is exposed to a 400 GeV/c high intensity proton beam from the SPS. [...]

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. [...]
