A series production of beam separation dipole, MBXF, is underway toward the High-Luminosity Large Hadron Collider upgrade (HL-LHC). So far, High Energy Accelerator Research Organization (KEK) have tested 4 series magnets in our own vertical cryostat, and their quench training performances have been successfully evaluated. [...]

Design and Metrological Characterization of a Digitizer for the Highest Precision Magnet Powering in the High Luminosity Large Hadron Collider
/ Beev, Nikolai (CERN ; Bratislava, Slovak Tech. U.) ; Cerqueira Bastos, Miguel (CERN) ; Martino, Michele (CERN) ; Valuch, Daniel (Bratislava, Slovak Tech. U. ; CERN) ; Palafox, Luis (Braunschweig, Phys. Tech. Bund.) ; Behr, Ralf (Braunschweig, Phys. Tech. Bund.)
A new digitizer, the HPM7177, which is a fundamental component of the signal chain for high precision measurement of particle accelerator magnet currents, is presented. It was designed to meet the unprecedented performance requirements for new 14 kA and 18 kA power converters (PCs) for the High Luminosity Large Hadron Collider (HL-LHC) project at CERN, particularly in terms of low-frequency noise and stability.

The Real-Time System for Distribution of Clock, Control and Monitoring Commands With Fixed Latency of the LHCb Experiment at CERN
/ Feo, Mauricio (CERN) ; Alessio, Federico (CERN) ; Durante, Paolo (CERN) ; Granado Cardoso, Luís (CERN) ; Vouters, Guillaume (Annecy, LAPP)
The Large Hadron Collider beauty (LHCb) experiment has gone through a major upgrade for LHC Run 3 at European Organization for Nuclear Research (CERN), scheduled to start in the middle of 2022. The entire readout system of the experiment has been replaced by front-end and back-end electronics that are able to record LHC events at the full LHC bunch crossing rate of 40 MHz. [...]

Application of the Universal Quench Detection System to the Protection of the High-Luminosity LHC Magnets at CERN
/ Steckert, Jens (CERN) ; Denz, Reiner (CERN) ; Mundra, Surbhi (CERN) ; Podzorny, Tomasz (CERN) ; Spasic, Jelena (CERN) ; Vancea, Dragos-Gabriel (CERN)
The Universal Quench Detection System (UQDS) has been primarily developed to detect quenches in various superconducting magnets of LHC’s High Luminosity upgrade (HL-LHC). The functionality of the system, which comprises insulated high-resolution digitizing front-end channels and a central processing element, is mainly defined by the configuration of the central FPGA (Field Programmable Gate Array). [...]

Thermal Neutron-Induced SEUs in the LHC Accelerator Environment
/ Cecchetto, Matteo (CERN) ; García Alía, Rubén (CERN) ; Wrobel, Frédéric (IES, Montpellier) ; Tali, Maris (CERN) ; Stein, Oliver (CERN) ; Lerner, Giuseppe (CERN) ; Biłko, Kacper (CERN) ; Esposito, Luigi (CERN) ; Bahamonde Castro, Cristina (CERN) ; Kadi, Yacine (CERN) et al.
In addition to high-energy hadrons, which include neutrons, protons, and pions above 20 MeV, thermal neutrons (ThNs) are a major concern in terms of soft error rate (SER) for electronics operating in the large hadron collider (LHC) accelerator at the European Organization for Nuclear Research (CERN). Most of the electronic devices still contain Boron-10 inside their structure, which makes them sensitive to ThNs. [...]

Investigation on the sensitivity of a 65nm Flash-based FPGA for CERN applications
/ Tsiligiannis, Georgios (CERN) ; Ferraro, Rudy (CERN) ; Danzeca, Salvatore (CERN) ; Masi, Alessandro (CERN) ; Brugger, Markus (CERN) ; Saigné, Frédéric (Montpellier U.)
The continuous need for upgrading the instrumentation and control electronics operating in various CERN experiments and along the LHC accelerator, has driven the qualification process of the new Flash-Based SmartFusion2 FPGAs; a leading candidate to be embedded in future systems. The radiation testing conditions have been chosen to fit the unique CERN environment, while the setup is carefully chosen to qualify all the subcomponents of the SoC FPGA that the engineering teams of CERN are considering for exploitation..

A 400A programmable linear current pulse generator
/ Gräwer, G (CERN) ; Cordobes Dominguez, F (CERN) ; Fowler, T (CERN) ; Voumard, N (CERN)
As part of the LHC Injector Upgrade (LIU) project, the production of a high-intensity proton beam in the Proton Synchrotron Booster (PSB) at CERN will be achieved by injecting a beam of H- ions from the new linear accelerator LINAC4. During the injection process the two electrons of the H- ions are removed with a stripping foil across which the machine orbit is shifted to fill the machine aperture with beam. [...]
