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.

Reconstruction of Transverse Phase Space From Transverse Feedback Data for Real Time Extraction of Vital LHC Machine Parameters
/ Kotzian, Gerd (CERN) ; Soderen, Martin (CERN) ; Solvang, Preben (CERN) ; Stopjakova, Viera (Bratislava, Inst. Phys.) ; Valuch, Daniel (CERN)
The LHC transverse feedback system (ADT) provides bunch by bunch, turn by turn, normalized and digitized beam position signals from four pick-ups per plane and for each beam. Together with already existing powerful computer-based observation systems, this data can be used to reconstruct in real-time the transverse phase space coordinates of the centre-of-charges, for each individual bunch.

Digital Low-Level RF System for the CERN Linac3 Accelerator
/ Valuch, Daniel (CERN) ; Alemany-Fernández, Reyes (CERN) ; Brischetto, Ylenia (CERN) ; Faeroe, Sindre (CERN) ; Piccinini, Giampaolo (CERN) ; Soderen, Martin (CERN)
A major consolidation of the aging RF system of the CERN Linac3, the ion source for the whole CERN accelerator chain, started during the Long Shutdown II. The main changes were an upgrade of the analogue Low-Level RF system (LLRF) and replacement of the 350 kW tube amplifiers by a solid-state equivalent. [...]

Achievements and Performance Prospects of the Upgraded LHC Injectors
/ Kain, Verena (CERN) ; Albright, Simon (CERN) ; Alemany-Fernández, Reyes (CERN) ; Angoletta, Maria Elena (CERN) ; Antoniou, Fanouria (CERN) ; Argyropoulos, Theodoros (CERN) ; Asvesta, Foteini (CERN) ; Balhan, Bruno (CERN) ; Barnes, Michael (CERN) ; Barrientos, Diego (CERN) et al.
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. [...]
