Evaluation of different scaling laws for dynamic aperture variation over time and intensity evolution in hadron storage rings / Montanari, Carlo Emilio
Two proposed fit models for Dynamic Aperture (DA) evolution have been studied in detail and applied to different numerical models and experimental data. [...]

Diffusive models and chaos indicators for non-linear betatron motion in circular hadron accelerators / Montanari, Carlo Emilio
Understanding the complex dynamics of beam-halo formation and evo- lution in circular particle accelerators is crucial for the design of current and future rings, particularly those utilizing superconducting magnets such as the CERN Large Hadron Collider (LHC), its luminosity upgrade HL-LHC, and the [...]

Determination of the Phase-Space Stability Border with Machine Learning Techniques / Van der Veken, Frederik (CERN) ; Akbari, Runa (CERN) ; Bogaert, Michiel (CERN) ; Fol, Elena (CERN) ; Giovannozzi, Massimo (CERN) ; Lowyck, Amy (CERN) ; Montanari, Carlo Emilio (CERN) ; Van Goethem, Wietse (CERN)
The dynamic aperture (DA) of a hadron accelerator is represented by the volume in phase space that exhibits bounded motion, where we disregard any disconnected parts that could be due to stable islands. To estimate DA in numerical simulations, it is customary to sample a set of initial conditions using a polar grid in the transverse planes, featuring a limited number of angles and using evenly distributed radial amplitudes. [...]

Using Machine Learning to Improve Dynamic Aperture Estimates / Van der Veken, Frederik F (CERN ; Malta U.) ; Giovannozzi, Massimo (CERN) ; Maclean, Ewen H (CERN ; Malta U.) ; Montanari, Carlo Emilio (Bologna U. ; CERN) ; Valentino, Gianluca (Malta U. ; CERN)
The dynamic aperture (DA) is an important concept in the study of nonlinear beam dynamics. Several analytical models used to describe the evolution of DA as a function of time, and to extrapolate to realistic time scales that would not be reachable otherwise due to computational limitations, have been successfully developed. [...]

Kinematic Fits to Determine Masses of Supersymmetric Particles at LHC / Schettler, Hannes (Hamburg U.)
In this thesis the method of kinematic fits is applied to determine the masses of supersymmetric particles. This is implemented by a constrained least square fit. [...]

Collimator Scan Based Beam Halo Measurements in LHC and HL-LHC / Hermes, Pascal (CERN) ; Giovannozzi, Massimo (CERN) ; Montanari, Carlo Emilio (CERN ; U. Manchester (main)) ; Morales Vigo, Sara (CERN ; Cockcroft Inst. Accel. Sci. Tech.) ; Rakic, Milica (Ecole Polytechnique, Lausanne) ; Redaelli, Stefano (CERN) ; Salvachúa, Belen (CERN)
Measurements in the CERN Large Hadron Collider (LHC) have indicated that the population of the transverse beam halo is greater than that of a Gaussian distribution. With the upcoming High Luminosity upgrade (HL-LHC), the stored beam energy in the beam halo could become large enough to threaten the integrity of the collimation system. [...]

Extended-Domain Tune-Scans for the HL-LHC Dynamic Aperture in Presence of Beam-Beam Effects / Kaltchev, Dobrin (TRIUMF) ; Karastathis, Nikolaos (CERN) ; Papaphilippou, Yannis (CERN) ; Pellegrini, Dario (CERN) ; McIntosh, E (CERN)
Simulations of the HL-LHC dynamic aperture (DA) at collision energy and in the presence of beam-beam effects (weak-strong approximation) have been performed to determine the dependence of DA on the working point in tune space. Both linear domains of working points are explored and two-dimensional ones which focus on more promising sub-regions near the diagonal. [...]
