Beam delivery of high-energy ion beams for irradiation experiments at the CERN Proton Synchrotron
/ Johnson, Eliott (CERN) ; Waets, Andreas (CERN) ; Imesch, Gil (CERN) ; Bilko, Kacper (CERN) ; Delrieux, Marc (CERN) ; Fraser, Matthew (CERN) ; Emriskova, Natalia (CERN) ; Arrutia Sota, Pablo Andreas (CERN) ; Garcia Alia, Ruben (CERN) ; Bass, Thomas (CERN)
Heavy-ion single event effect (SEE) test facilities are critical in the development of microelectronic components that will be exposed to the ionizing particles present in the hostile environment of space. CHARM High-energy Ions for Micro Electronics Reliability Assurance (CHIMERA) and HEARTS have developed a high-energy ion beam capable of scanning a wide range of Linear Energy Transfer (LET) at low intensities to study ionization effects on space-bound technology using CERN's Proton Synchrotron (PS).

The CERN SPS Low Level RF feedback with amplitude and frequency modulation
/ Hagmann, Gregoire (CERN) ; Spierer, Arthur (CERN) ; Egli, Julien (CERN) ; Baudrenghien, Philippe (CERN)
The CERN SPS Low Level RF (LLRF) has undergone a major upgrade, including the complete redesign of the 200 MHz Cavity-Controllers [1,2] and the Beam-Control [3]during the Long Shutdown two (LS2) in 2018-21. Two major goals motivated the upgrade, first the required doubling of the proton beam intensity injected from the Super Proton Synchrotron (SPS) for the High Luminosity Large HadronCollider (HL-LHC) project, second the implementation of the slip-stacking of two families of ions bunches, 100 ns spacing, to generate a 50 ns spacing after interleaving.

New Generation Energy Extraction Systems for the High-Luminosity Large Hadron Collider Project at CERN
/ Panev, B I (CERN) ; Pojer, M (CERN) ; Mateos, F Rodriguez (CERN) ; Coelingh, G J (CERN) ; Grigorov, M (CERN) ; Georgakakis, S (CERN) ; Borkowski, P (Lodz, Tech. U.) ; Rodak, M (Lodz, Tech. U.) ; Sienicki, A (Lodz, Tech. U.) ; Wojcik, F (Lodz, Tech. U.)
A new, high-speed, and high-current DC switching technology based on commercial medium-voltage vacuum interrupters was explored and successfully validated for future use in the energy extraction systems (EES) to protect the superconducting magnet circuits at CERN. In the development process, two types of systems were produced, one rated for 2 kA and another for 600 A. [...]

Analysis of the Panofsky-Wenzel Theorem in pillbox cavities with a beam pipe
/ Wroe, Laurence (CERN) ; Latina, Andrea (CERN) ; Southerby, Matthew (Lancaster U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Apsimon, Robert (Cockcroft Inst. Accel. Sci. Tech. ; Lancaster U.) ; Stapnes, Steinar (CERN) ; Wuensch, Walter (CERN)
In this paper, we derive the multipolar form of the change in transverse and longitudinal momenta of an ultra-relativistic charged particle that traverses a harmonic TM$_{mn0}$ mode in a pillbox cavity with a beam pipe. The relevant equations are first formalised before presenting results from the numerical integration of RF cavity field maps. [...]

The reinforcement learning for autonomous accelerators collaboration
/ Santamaria Garcia, Andrea (KIT, Karlsruhe) ; Eichler, Annika (DESY) ; Xu, Chenran (KIT, Karlsruhe) ; Kaiser, Jan (DESY) ; Scomparin, Luca (KIT, Karlsruhe) ; Schenk, Michael (CERN) ; Pochaba, Sabrina (Unlisted, AT) ; Hirlaender, Simon (U. Salzburg (main))
Reinforcement Learning (RL) is a unique learning paradigm that is particularly well-suited to tackle complex control tasks, can deal with delayed consequences, and can learn from experience without an explicit model of the dynamics of the problem. These properties make RL methods extremely promising for applications in particle accelerators, where the dynamically evolving conditions of both the particle beam and the accelerator systems must be constantly considered.

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.

The Large Hadron Collider (LHC) includes eight main dipole circuits, each containing 154 superconducting magnets. We are carrying out simulations of the electromagnetic thermal behavior of these circuits, together with experimental tests and continuous monitoring, to ensure their safe operation and to further improve our understanding.

Understanding Inductor-Originated Single-Event Frequency Transients in CMOS LC -Tank Oscillators: Causes, Effects, and System Impacts
/ Adom-Bamfi, Gideon (Leuven U.) ; Ma, Qichao (Leuven U.) ; Biereigel, Stefan (CERN) ; Leroux, Paul (Leuven U.) ; Prinzie, Jeffrey (Leuven U.)
Single-event frequency transients (SEFTs) in integrated complementary metal oxide semiconductor (CMOS) LC-tank voltage-controlled oscillator (VCO) and digitally-controlled oscillator (DCO), widely used in frequency synthesizer circuits, have recently been observed and linked to single-event effects (SEEs) in on-chip planar spiral inductors. This work provides an explanation of the underlying causes of these transients, presenting, for the first time, a general model to characterize their behavior and examine their system-level impact.
