Slow extracted spill ripple control in the CERN SPS using adaptive Bayesian optimisation
/ Kain, Verena (CERN) ; Effinger, Ewald (CERN) ; Follin, Fabio (CERN) ; Velotti, Francesco (CERN) ; Fraser, Matthew (CERN) ; Schenk, Michael (CERN) ; Madysa, Nico (Darmstadt, GSI) ; Arrutia Sota, Pablo Andreas (CERN)
The CERN Super Proton Synchrotron (SPS) offers slow-extracted, high-intensity proton beams at 400 GeV/c for 3 fixed targets in the CERN North Experimental Area (NA) with a spill length of about 5 seconds. Since first commissioning in the late seventies, the NA has seen a steady increase in users, many of which requiring improved spill quality control. [...]

Optics rematching between TT24 and P42 primary beam lines within the HI-ECN3 study project at CERN
/ Gorn, Aleksandr (CERN) ; Bracco, Chiara (CERN) ; Velotti, Francesco (CERN) ; Bernhard, Johannes (CERN) ; Nevay, Laurence (CERN) ; Dyks, Luke (Oxford U.) ; Fraser, Matthew (CERN)
The High Intensity ECN3 (HI-ECN3) study project aims to increase the intensity of the proton beam delivered to a new experimental facility housed in the ECN3 underground cavern in CERN’s North Area up to the ~4e+13 ppp (protons per pulse) and up to ~4e+19 POT (protons on target) per year. The increase necessitates upgrades of the primary beam transfer lines coming from SPS directly to the new Target Complex upstream of ECN3. [...]

Beam optics modelling of slow-extracted very high-energy heavy ions from the CERN Proton Synchrotron for radiation effects testing
/ Johnson, Eliott (CERN) ; Bilko, Kacper (CERN) ; Delrieux, Marc (CERN) ; Esposito, Luigi Salvatore (CERN) ; Emriskova, Natalia (CERN) ; Fraser, Matthew (CERN) ; Garcia Alia, Ruben (CERN) ; Arrutia Sota, Pablo Andreas (CERN) ; Waets, Andreas (CERN)
Testing of space-bound microelectronics plays a crucial role in ensuring the reliability of electronics exposed to the challenging radiation environment of outer space. This contribution describes the beam optics studies carried out for the run held in November 2023 in the context of the CERN High-Energy Accelerators for Radiation Testing and Shielding (HEARTS) experiment.

Upgrade of the PS booster-to-ISOLDE beam transfer line to facilitate an increase in proton driver energy

Following the successful completion of the LHC Injectors Upgrade (LIU) project, since 2021 the Proton Synchrotron (PS) Booster has served the LHC injector chain with protons at an increased kinetic energy of 2 GeV. An upgrade of the ISOLDE (Isotope Separator On-Line DEvice) facility has long been considered to produce radioactive ion beams with a higher energy proton driver beam. [...]

Improvements of the SPS slow extraction electrostatic septum
/ Lackner, Friedrich (CERN) ; Prost, Antoine (CERN) ; Balhan, Bruno (CERN) ; Pirozzi, Fabrizio (CERN) ; Vincke, Helmut (CERN) ; Borburgh, Jan (CERN) ; Kawa, Krzysztof (CERN ; AGH-UST, Cracow) ; Jorat, Louise Olivia (CERN) ; Fraser, Matthew (CERN) ; Roudaut, Noah (CERN ; UTBM, Belfort)
The impact of high-flux protons on the inherent beam loss in the slow extraction straight from SPS towards the North Area has been recently discussed and potential improvements have been proposed. These solutions are mainly aiming to reduce the high component activation and related reduction of lifetime, as well as observed non-straightness in the anode body. [...]

Enhancing CERN-SPS slow extraction efficiency: meta Bayesian optimisation in crystal shadowing
/ Velotti, Francesco (CERN) ; Matheson, Eloise (CERN) ; Esposito, Luigi Salvatore (CERN) ; Fraser, Matthew (CERN) ; Solis Paiva, Santiago (CERN) ; Kain, Verena (CERN)
The Super Proton Synchrotron at CERN serves the fixed-target experiments of the North Area, providing protons and ions via slow extraction, and employs the crystal shadowing technique to significantly minimize losses. Over the past three operational years, the use of a crystal, positioned upstream of the electrostatic septum to shadow its blade, has allowed to achieve a 25% reduction in losses. [...]

Performance Improvement Studies of the Fixed Target Beams along the CERN Injector Chain

Within the LHC Injectors Upgrade (LIU) project, LHC injectors received major upgrades that resulted in an unprecedented beam brightness. In the framework of the Physics Beyond Colliders (PBC) study, the full potential of the upgraded injectors is being explored for the improvement of the Fixed Target (FT) beams as well. [...]

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. [...]
