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. [...]

Feasibility study of the Alice fixed-target experiment with HL-LHC lead ion beams based on crystal-assisted beam Halo splitting / Patecki, Marcin (Warsaw U. of Tech. (main)) ; Monikowska, Marta (Warsaw U. of Tech. (main))
The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) is the world's largest and most powerful particle accelerator, colliding beams of protons and lead ions at energies up to 7 ZTeV. ALICE is one of the detector experiments optimized for heavy-ion collisions.A fixed-target experiment in ALICE is considered to collide a portion of the beam halo, split using a bent crystal, with an internal target placed a few meters upstream of the detector.

ESS WS scintillator system design and test results / Grishin, Viatcheslav (ESS, Lund) ; Aleksandrov, Alexander (ORNL, Oak Ridge (main)) ; Boehme, Christian (Julich, Forschungszentrum) ; Derrez, Clement (ESS, Lund) ; Thomas, Cyrille (ESS, Lund) ; Bergman, Edvard (ESS, Lund) ; Donegani, Elena (ESS, Lund) ; Kocevar, Hinko (ESS, Lund) ; Emery, Jonathan (CERN) ; Sirvent, Jose (CERN) et al.
The WS superconducting systems are based on scintillator detectors and wavelength shifting fibers are mounted on the beam pipe. The detectors are coupled to long haul optical fibers, which carry the signals to custom front end electronics sitting in controls racks at the surface. [...]

Effects of dipole power converter ripple during empty-bucket channelling / Arrutia Sota, Pablo Andreas (U. Oxford (main)) ; Velotti, Francesco (CERN) ; Fraser, Matthew (CERN)
In 2023, an RF technique known as empty-bucket channelling was implemented operationally at the CERN Super Proton Synchrotron (SPS) to improve the quality of the spill provided to the North Area experiments. Empty-bucket channelling suppresses particle-flux variations during resonant slow extraction by accelerating particles between empty RF buckets and rapidly displacing particles into the tune resonance via chromatic coupling.

CERN Proton Synchrotron (PS) is featured with 100 C-shaped combined-function Main Units (MUs) magnets with a complicated pole shape. The operation and the modelling of the PS-MUs has been historically carried out with empirical beam-based studies. [...]

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.

Development of a fast pulsed magnet system for the MYRRHA collaboration / Ruf, Johannes (CERN) ; Standen, Dylan (CERN) ; van de Walle, Jarno (SCK-CEN, Mol) ; Barnes, Michael (CERN) ; Diaz Zumel, Miguel (CERN) ; Dams, Ot (SCK-CEN, Mol) ; Kramer, Thomas (CERN)
In the framework of the MYRRHA programme, a large-scale Accelerator Driven System (ADS) being implemented by SCK CEN in Belgium, a fast pulsed magnet system is being designed and specified at CERN. A complete design study has been performed to develop the specifications and drawings for a kicker magnet, as well as the associated pulse generator to deflect the 100 MeV proton beam. [...]

Innovative bulge test setup to characterize thin beam vacuum windows / Giovinco, Valentina (CERN) ; Morrone, Marco (CERN) ; Ferreira Somoza, Jose (CERN) ; Garion, Cedric (CERN)
As part of the International Muon Collider study, a beam vacuum window is being developed at CERN. It is required for the final cooling, where the charged particles travel from the vacuum chamber to the absorber; here, the beam loses momentum to cross a second window entering in a RF cavity that increases the longitudinal momentum.

Neutron production using compact linear electron accelerators / Olivares Herrador, Javier ; Wroe, Laurence ; Latina, Andrea ; Wuensch, Walter ; Corsini, Roberto ; Stapnes, Steinar ; Fuster-Martinez, Nuria ; Gimeno-Martinez, Benito ; Esperante, Daniel
Many reactor-based neutron sources are planned to shut down in the near future, and this is despite the increasing demand for neutron beamlines for a wide range of scientific and industrial applications. Consequently, compact accelerator-based neutron sources arise as a competitive alternative that could meet the need for medium-flux fission or spallation sources. [...]
