Coupling local and global rf feedback loops for macroparticle tracking simulations / Karlsen-Baeck, B E (Rome U. ; CERN) ; Argyropoulos, T (CERN) ; Flowerdew, J (CERN) ; Intelisano, L (CERN) ; Karpov, I (CERN) ; Lasheen, A (CERN) ; Timko, H (CERN)
Radio frequency (rf) control loops are vital components for the optimal operation of rf systems in synchrotron particle accelerators. Modeling these systems in macroparticle tracking simulations provides improved understanding of the complex interaction between the control loops, the beam-induced voltages in the rf cavities, and the circulating beam.

Development of radiation-tolerant beam imaging via multimode fiber and synthetic data-driven machine learning / Xu, Q (Cockcroft Inst. Accel. Sci. Tech. ; CERN ; U. Liverpool (main)) ; Zhang, H D (Cockcroft Inst. Accel. Sci. Tech. ; U. Liverpool (main)) ; Trad, G (CERN) ; Hill, A (Cockcroft Inst. Accel. Sci. Tech. ; U. Liverpool (main)) ; Roncarolo, F (CERN) ; Welsch, C P (Cockcroft Inst. Accel. Sci. Tech. ; U. Liverpool (main))
Transverse beam profile monitoring in high-radiation areas is challenging due to camera degradation. A proposed solution employs a multimode fiber (MMF) to relay optical signals from the radiation zone to a shielded area, where a standard CMOS camera can operate safely. [...]

Development and Characterization of a Radiation-Tolerant Power Supply for Beam Instrumentation / Vigano, William (CERN) ; Zamantzas, Christos (CERN) ; Effinger, Ewald (CERN) ; Meyer, Jean Michel (CERN) ; Michelis, Stefano (CERN)
CERN’s Beam Instrumentation Group is developing a mini-crate to host the future Beam Loss Monitor (BLM) and Beam Positioning Monitor (BPM) systems acquisition electronics at HL-LHC and SPS accelerators. For this purpose, a new power supply has been designed to meet the low noise requirements, high reliability, and availability standards for these harsh radioactive environments. [...]

Optical beam loss monitor installed at the SPS slow extraction region / King, Montague (CERN ; U. Liverpool (main)) ; Benitez Berrocal, Sara (CERN) ; Effinger, Ewald (CERN) ; Esteban, Jose (CERN) ; Kearney, Joe (CERN) ; Meyer, Jean Michel (CERN) ; Salvachua, Belen (CERN) ; Welsch, Carsten (U. Liverpool (main) ; Cockcroft Inst. Accel. Sci. Tech.) ; Wolfenden, Joseph (U. Liverpool (main) ; Cockcroft Inst. Accel. Sci. Tech.)
An optical beam loss monitor (oBLM) has recently been installed at the slow extraction region of the Super Proton Synchrotron (SPS) at CERN. The oBLM offers a new method for detecting beam losses at the SPS by utilizing the Cherenkov radiation emitted during beam loss interactions with an optical fibre. [...]

Design and expected performance of the new BPM systems for AWAKE Run $^{2}$C / Stant, Laurence (CERN) ; Boccardi, Andrea (CERN) ; Bogey, Thierry (CERN) ; Degl'Innocenti, Irene (CERN) ; Jevtic, Aleksandar (CERN) ; Krupa, Michal (CERN) ; Mazzoni, Stefano (CERN) ; Pakuza, Collette (CERN)
The AWAKE facility at CERN uses novel proton beam-driven plasma wakefields to accelerate electron bunches over a 10 m plasma source. The facility will soon be rebuilt to study methods to improve the quality of the accelerated electron beam, requiring better resolution from the proton BPMs. [...]

Research and development of a radiation hard beam profile monitor for use in the CERN North Area secondary beamlines / Ortega, Inaki (CERN) ; Danielsson, Hans (CERN) ; Gerbershagen, Alexander (PNSensor GmbH) ; Larsen, Robert (CERN ; PNSensor GmbH) ; McLean, Mark (CERN ; Groningen, KVI) ; Moser, Benjamin (CERN) ; Zamkovsky, Michal (CERN)
The CERN Beam Instrumentation group is currently investigating a radiation-hard beam profile monitor for the CERN North Area. Our main efforts are now focused on straw tubes, a type of wire chamber detector that offers the advantage of being vacuum-compatible and easily equipped with in/out motorisation. [...]

Upgrade and evolution of the ad target beam imaging system at CERN: a two-year performance analysis / Burger, Stephane (CERN) ; Roncarolo, Federico (CERN) ; Martínez Samblas, Javier (CERN) ; Gonzalez-Berges, Manuel (CERN)
During CERN’s Long Shutdown 2 (LS2) in 2022, the Anti-Proton Decelerator (AD) target area underwent major renovations, including a significant upgrade to its beam imaging system. The previous tube-based camera, used in a high-radiation environment, had limitations in sensitivity and resolution for continuous measurements.The upgraded design uses an innovative in-air light-emitting screen mechanically coupled to the AD target, monitored by a digital camera through a 20-meter optical line from a radiation-safe zone.
