Experimental confirmation of the impedance reduction campaign in the CERN SPS
/ Argyropoulos, Theodoros (CERN) ; Damerau, Heiko (CERN) ; Karpov, Ivan (CERN) ; Lasheen, Alexandre (CERN) ; Papotti, Giulia (CERN)
Measurements of the very long single bunch spectrum with RF off, were started in the SPS in 2012 to identify the main impedance sources responsible for both single and multi-bunch beam instabilities observed during operation. The impedance of the vacuum flanges with a strong peak at 1.4 GHz was identified and proven from simulations to limit the beam intensities required for the High-Luminosity LHC (HL-LHC). [...]

Operational improvements and upgrades of the CLEAR user facility
/ Korysko, Pierre (Oxford U.) ; Malyzhenkov, Alexander (CERN) ; Gilardi, Antonio (CERN) ; Aksoy, Avni (CERN) ; Robertson, C (Oxford U.) ; Granados, Eduardo (CERN) ; Najmudin, I (Oxford U.) ; Wroe, Laurence (CERN) ; Martinez-Calderon, Miguel (CERN) ; Corsini, Roberto (CERN) et al.
The CERN Linear Accelerator for Research (CLEAR) at CERN is a user facility providing a 200 MeV electron beam for accelerator R&D; and irradiation studies, including medical applications. In this paper we will outline the most recent improvements in CLEAR operation and beam control and delivery, and describe the upgrades under way, giving an update of their current status. [...]

Testing aspects of the CERN beam interlock system prior to installation in the accelerator
/ Colinet, Antoine (CERN) ; Martin, Christophe (CERN) ; Romera, Iván (CERN) ; Uythoven, Jan (CERN) ; Secondo, Raffaello (CERN) ; Bolton, Samuel (CERN) ; Guasch-Martinez, Josep (CERN)
The Beam Interlock System (BIS) is the backbone of the machine protection system throughout the accelerator complex at CERN, from LINAC4 to the LHC. After 15 years of flawless operation, a new version of the BIS is currently being produced and will be installed in the LHC, SPS and North Area during CERN’s Long Shutdown 3, planned to start in 2026.

High fidelity numerical modelling and condition monitoring applied to septum magnets at CERN
/ Kawa, Krzysztof (CERN ; AGH-UST, Cracow) ; Szumlak, Tomasz (AGH-UST, Cracow) ; Kokkinos, Charilaos (Unlisted, GR) ; Lackner, Friedrich (CERN)
The CERN Accelerator Beam Transfer group has recently launched a study to investigate the life cycles of pulsed septum magnets. The development is aiming to enhance the prediction of anomalies, leading to reduced life cycles of these beam transfer equipment. [...]

ELISA: a compact linear accelerator for societal applications
/ Pasino, Eleonora (CERN) ; Lombardi, Alessandra (CERN) ; Grudiev, Alexej (CERN) ; Montesinos, Eric (CERN) ; Di Lorenzo, Francesco (CERN) ; Lallement, Jean-Baptiste (CERN) ; Koopmans, Marten (CERN) ; Mathot, Serge (CERN)
The experience gained at CERN by the R&D; for LINAC4 has been exported to medical and societal applications. With an innovative design of the Radio Frequecy Quadrupole (RFQ) at high frequencies, it is possible to build very com- pact structures, reproducible in industry and with the po- tential of full portability.
