Empty-bucket techniques for spill-quality improvement at the CERN Super Proton Synchrotron / Arrutia Sota, Pablo A (CERN) ; Fraser, Matthew A (CERN) ; Hagmann, Gregoire (CERN) ; Kain, Verena (CERN) ; Papotti, Giulia (CERN) ; Spierer, Arthur (CERN) ; Velotti, Francesco M (CERN) ; Burrows, Philip N (JAI, UK) ; Piandani, Roberto (San Luis Potosi U.)
Synchrotrons can provide long spills of particles by employing resonant extraction where the circulating beam is slowly ejected over thousands to millions of turns by exploiting the amplitude growth caused by a transverse resonance. In the CERN Super Proton Synchrotron (SPS), this method is used to satisfy the experimental requests of the North Area. [...]

The LHC Injectors Upgrade (LIU) project was put in place between 2010 and 2021 to increase the intensity and brightness in the LHC injectors to match the challenging requirements of the High-Luminosity LHC (HL-LHC) project, while ensuring reliable operation of the injectors complex up to the end of the HL-LHC era (ca. 2040).

An improved procedure for energy matching between PS and SPS at CERN / Papotti, Giulia (CERN) ; Cettour Cave, Stephane (CERN) ; Follin, Fabio (CERN) ; Spierer, Arthur (CERN)
Energy matching between two hadron synchrotrons is the adjustment of the magnetic bending fields and beam momentum to obtain a correct transfer between the two. Conventionally, energy matching is achieved by turning off the RF system and measuring the revolution frequency of the de-bunching beam in the receiving accelerator. [...]

SPS fixed target spill quality improvements in the longitudinal plane / Papotti, Giulia (CERN) ; Spierer, Arthur (CERN) ; Quartullo, Danilo (CERN) ; Hagmann, Gregoire (CERN) ; Karpov, Ivan (CERN) ; Piandani, Roberto (San Luis Potosi U.)
The SPS proton fixed target beams are spilled via a third integer resonant extraction, for which high momentum spread is beneficial. To increase the momentum spread prior to the slow extraction, the bunches are stretched at the unstable phase by inverting the sign of the RF voltage. [...]

This paper is the second of a series of three on the Super Proton Synchrotron (SPS) Low Level RF (LLRF) upgrade. It covers the 200MHz Cavity-Controller part, that is responsible for the regulation of the accelerating field in a single SPS cavity. [...]

The Super Proton Synchrotron (SPS) Low Level RF (LLRF) has been completely upgraded during the CERN long shutdown (LS2, 2019-2020). The old NIM and VME based, mainly analog system has been replaced with modern digital electronics implemented on a MicroTCA platform. [...]

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. [...]

In 2021 the Super Proton Synchrotron has been recommissioned after a complete renovation of its low level RF system (LLRF). The new system has largely moved to digital signal processing implemented as a set of functional blocks (IP cores) in Field Programmable Gate Arrays (FPGAs) with associated software to control them.
