Advancements and Applications of Cooling Simulation Tools: A Focus on Xsuite
/ Kruyt, Peter (CERN ; Frankfurt U.) ; Franchetti, Giuliano (Darmstadt, GSI ; CERN ; Frankfurt U.) ; Gamba, Davide (CERN)
his paper presents recent advancements in cooling simulation tools in Xsuite, which is a new particle accelerator simulation code developed at CERN. An electron cooling module, based on the Parkhomchuk model, has been implemented and benchmarked against Betacool using parameters of the LEIR e-cooler at CERN. [...]

Measurement of Transverse Statistical Dependence for Non-Gaussian Beam Distributions via Resonances in the CERN PSB
/ Lamb, Elleanor (CERN ; EPFL, Lausanne, FSL) ; Asvesta, Foteini (CERN) ; Bartosik, Hannes (CERN) ; Sterbini, Guido (CERN)
This work addresses the origins and the effects of the statistical dependence in non-Gaussian beam distributions with the ultimate goal to identify the most representative case for tracking simulations across the CERN accelerator complex. Starting from the observation that non-Gaussian heavy-tailed transverse beam profiles can be reconstructed from 4D phase space distributions under two different conditions (statistical independence or dependence in the x-y plane), we consider space charge dominated beams interacting with the lattice nonlinear resonances to perform measurements to study the mechanisms that lead to non-Gaussian distributions.

Experimental Investigations on the High-Intensity Effects Near the Half-Integer Resonance in the PSB
/ Prebibaj, Tirsi (CERN) ; Antoniou, Fanouria (CERN) ; Asvesta, Foteini (CERN) ; Bartosik, Hannes (CERN) ; Franchetti, Giuliano (Darmstadt, GSI)
Space charge effects are the main limitation for the brightness performance of the Proton Synchrotron Booster (PSB) at CERN. Following the upgrades of the LHC Injectors Upgrade (LIU) project, the PSB delivered unprecedented brightness even exceeding the projected target parameters. [...]

The Tracking Code RF-Track and Its Application
/ Latina, Andrea (CERN)
RF-Track is a CERN-developed particle tracking code that can simulate the generation, acceleration, and tracking of beams of any species through an entire accelerator, both in realistic field maps and conventional elements. RF-Track includes a large set of single-particle and collective effects: space-charge, beam-beam, beam loading in standing and travelling wave structures, short- and long-range wakefield effects, synchrotron radiation emission, multiple Coulomb scattering in materials, and particle lifetime. [...]

Benchmarking of PATH and RF-Track in the Simulation of Linac4
/ Bellodi, Giulia ; Lallement, Jean-Baptiste ; Latina, Andrea ; Lombardi, Alessandra
A benchmarking campaign has been initiated to compare PATH and RF-Track in modelling high-intensity, low-energy hadron beams. The development of extra functionalities in RF-Track was required to handle an unbunched beam from the source and to ease the user interface. [...]

Pushing High Intensity and High Brightness Limits in the CERN PSB after the LIU Upgrades
/ Asvesta, Foteini (CERN) ; Albright, Simon (CERN) ; Bartosik, Hannes (CERN) ; Bracco, Chiara (CERN) ; Di Giovanni, Gian Piero (CERN) ; Prebibaj, Tirsi (CERN)
After the successful completion of the LHC Injectors Upgrade (LIU) project, the CERN Proton Synchrotron Booster (PSB) has produced beams with up to two times higher brightness. However, the efforts to continuously improve the beam quality for the CERN physics experiments are ongoing. [...]

Summary of the Working Group A: Beam Dynamics in Rings
/ Bartosik, Hannes (CERN) ; Rumolo, Giovanni (CERN) ; Vay, Jean-Luc (LBL, Berkeley) ; Wang, Na (Beijing, Inst. High Energy Phys.)
The HB-2023 workshop at CERN from October 9 to 13, 2023 is the continuation of the series of workshops, which started in 2002 at FNAL and rotates every two years between America, Europe and Asia. This contribution summarises the main highlights from Working Group A, Beam Dynamics in Rings, in terms of progress and challenges in the achievement of ever higher intensity and brightness hadron beams in accelerator rings around the world..

Analytical and Numerical Studies on Kicked Beams in the Context of Half-Integer Studies
/ Franchetti, Giuliano (Darmstadt, GSI ; Goethe U., Frankfurt (main) ; Helmholtz Res. Acad. Hesse for FAIR) ; Asvesta, Foteini (CERN) ; Bartosik, Hannes (CERN) ; Prebibaj, Tirsi (CERN)
In the context of the half-integer studies an investigation of the dynamics of the kicked beam has revealed surprising properties. The coupling of space charge with chromatic- ity in addition to usual damping/non-damping dynamics, exhibits new properties typical of a linear coupling. [...]
