First operational results of new real-time magnetic measurement systems for accelerator control
/ Giloteaux, David (CERN) ; Buzio, Marco (CERN) ; Bonora, Matthias (CERN) ; Di Capua, Vincenzo (CERN) ; Albright, Simon (CERN) ; Damerau, Heiko (CERN) ; Di Giovanni, Gian Piero (CERN) ; Huschauer, Alexander (CERN)
A new real-time measurement system for accelerator control, named FIRESTORM (Field In Real-time Streaming from Online Reference Magnets), to measure the integrated bending field has been recently deployed and commissioned in six synchrotron rings at CERN. We present the operational experience during the preparation phase and the restart of the accelerator complex for Run 3, focusing on the metrological performance of the new sensors and electronics, and on the lessons learned during commissioning.

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. [...]

Two-Dimensional Longitudinal Painting at Injection into the CERN PS Booster
/ Albright, Simon (CERN) ; Asvesta, Foteini (CERN) ; Bielawski, Bartosz Przemyslaw (CERN) ; Bracco, Chiara (CERN) ; Skowroński, Piotr (CERN) ; Wegner, Rolf (CERN)
To inject highest beam intensities at the transfer from Linac4 into the four rings of the PS Booster (PSB) at CERN, protons must be accumulated during up to 148 turns in total. With the conventional, fixed chopping pattern this process results in an approximately rectangular distribution in the longitudinal phase space. [...]
