Radiation test of commercial of the shelf (COTS) optical transceivers in the frame of the beam position monitor (BPM) consolidation project for the Large Hadron Collider (LHC)
/ Marin, M Barros (CERN) ; Boccardi, A (CERN) ; Ozdogan, S Can (CERN) ; Danzeca, S (CERN) ; Ferraro, R (CERN) ; Scialdone, A (CERN)
The consolidation of the Large Hadron Collider (LHC) beam position monitor (BPM) requires the deployment of about 5000 single-mode radiation-tolerant optical transmitters, working at 10 Gbps during 20 years of operation. While the use of the custom devices being designed at CERN remains the baseline for the project, 8 commercial of the shelf (COTS) optical transceivers have been evaluated as an alternative. [...]

Developing electronics boards through standardisation, specialised tools and collaboration
/ Boccardi, Andrea (speaker) (CERN)
The Beam Instrumentation Group (SY-BI) is responsible for designing, building and maintaining the instruments that allow observation of the particle beams and the measurement of related parameters for all CERN accelerators and transfer lines. Those instruments are often highly specialised and require the design of dedicated electronics, especially but not only for the elements exposed to radiation.
This contribution will illustrate the type of electronics boards and systems designed in SY-BI, the specification and review process in place in the group, the tools used, the CERN services we rely on and the network of collaborations with other groups that supports those designs..

A Snapshot of CERN Beam Instrumentation R&D; Activities
/ Lefèvre, Thibaut (CERN) ; Alves, Diogo (CERN) ; Boccardi, Andrea (CERN) ; Jackson, Stephen (CERN) ; Roncarolo, Federico (CERN) ; Storey, James (CERN) ; Veness, Raymond (CERN) ; Zamantzas, Christos (CERN)
The CERN accelerator complex stands out as an unique scientific tool, distinguished by its scale and remarkable diversity. Its capacity to explore a vast range of beam parameters is truly unparalleled, spanning from the minute energies of around a few keV and microampere antiproton beams, decelerated within the CERN antimatter factory, to the 6.8 TeV high-intensity proton beams that race through the Large Hadron Collider (LHC).

Beam Instrumentation Simulation in Python
/ Gonzalez-Berges, Manuel (CERN) ; Alves, Diogo (CERN) ; Boccardi, Andrea (CERN) ; Chariton, Vasileios (CERN) ; Degl'Innocenti, Irene (CERN) ; Jackson, Stephen (CERN) ; Martínez Samblas, Javier (CERN)
The design of acquisition electronics for particle accelerator systems relies on simulations in various domains. System level simulation frameworks can integrate the results of specific tools with analytical models and stochastic analysis. [...]

HL-LHC BPM electronics development as a case study for direct digitization and integrated processing techniques in accelerator instrumentation
/ Degl'Innocenti, Irene (CERN) ; Boccardi, Andrea (CERN) ; Bett, Douglas (JAI, UK) ; Krupa, Michal (CERN)
The technological evolution of analog-to-digital and digital-to-analog converters increases the amount of data that can be processed in the digital domain. Therefore, direct digitization enables many advanced signal processing techniques and is attracting more and more attention in the field of accelerator instrumentation. [...]

Improvements on the LHC Interlock BPM system

The LHC interlock BPM system is used as part of the beam abort system to insure that beam trajectories in those regions are conform with a safe extraction of the beams from the main ring to the dump lines. After more than 10 years of operation, the system has shown some limitations in bandwidth and dynamic range and a study was initiated to look for improvements. [...]

Achievements and Performance Prospects of the Upgraded LHC Injectors

To provide HL-LHC performance, the CERN LHC injector chain underwent a major upgrade during an almost 2-year-long shutdown. In the first half of 2021 the injectors were gradually re-started with the aim to reach at least pre-shutdown parameters for LHC as well as for fixed target beams. [...]

Signal Processing Architecture for the HL-LHC Interaction Region BPMs
/ Bett, Douglas R (Oxford U.) ; Boccardi, Andrea (CERN) ; Degl'Innocenti, Irene (CERN) ; Krupa, Michal (CERN)
In the HL-LHC era, the Interaction Regions around the ATLAS and CMS experiments will be equipped with 24 new Beam Position Monitors (BPM) measuring both counter-propagating beams in a common vacuum chamber. Numerical simulations proved that, despite using new high-directivity stripline BPMs, the required measurement accuracy cannot be guaranteed without bunch-by-bunch disentanglement of the signals induced by both beams. [...]

Commissioning of ALPS, the New Beam Position Monitor System of CERN’s Super Proton Synchrotron
/ Boccardi, Andrea (CERN) ; Albertone, Joel (CERN) ; Barros Marin, Manoel (CERN) ; Bogey, Thierry (CERN) ; Kain, Verena (CERN) ; Li, Kevin S B (CERN) ; Malinowska, Patrycja A (CERN ; AGH-UST, Cracow) ; Topaloudis, Athanasios (CERN) ; Wendt, Manfred (CERN)
The Super Proton Synchrotron (SPS) is both, the final machine in the pre-accelerator chain of the Large Hadron Collider (LHC) at CERN, and a machine providing several experiments with proton and ion beams. In the framework of CERN’s LHC Injectors Upgrade (LIU) project, aimed at improving the performances of the pre-accelerators in view of the high-luminosity upgrade of the LHC, the Beam Position Monitor (BPM) system of the SPS was redesigned during Run 2 of the LHC and deployed during the subsequent Long Shutdown 2 (LS2).
