A New Beam Loading Compensation and Blowup Control System Using Multi-Harmonic Digital Feedback Loops in the CERN Proton Synchrotron Booster / Barrientos, Diego (CERN) ; Albright, Simon (CERN) ; Angoletta, Maria Elena (CERN) ; Findlay, Alan (CERN) ; Jaussi, Michael (CERN) ; Molendijk, John (CERN)
As part of the LHC Injectors Upgrade, the CERN Proton Synchrotron Booster (PSB) has been upgraded with new wide-band Finemet cavities and a renovated Low-Level Radio Frequency system with digital cavity controllers implemented in FPGAs. Each controller synchronously receives the computed revolution frequency, used to generate 16 harmonic references. [...]

Direct Impedance Measurement of the CERN PS Booster Finemet Cavities / Albright, Simon (CERN) ; Angoletta, Maria Elena (CERN) ; Barrientos, Diego (CERN) ; Findlay, Alan (CERN) ; Jaussi, Michael (CERN) ; Molendijk, John (CERN)
Over CERN’s Long Shutdown 2, the conventional ferrite-loaded cavities of the PS Booster were replaced with wide-band Finemet-loaded cavities. The Finemet cavities bring many operational advantages, but also represent a significant broadband impedance source. [...]

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. [...]
