Optimisation of integrated luminosity in a circular collider with application to the LHC Run 2 / Capoani, F (INFN, Bologna ; Bologna U. ; CERN) ; Bazzani, A (Bologna U.) ; Giacobbe, B (INFN, Bologna) ; Giovannozzi, M (CERN)
Circular collider designs are tailored to maximise luminosity delivered to experimental detectors, effectively utilising the charged beams that have been accelerated for collisions. In reality, the key metric for the effective operation of a circular collider is the integrated luminosity provided to the experiments, which can significantly differ from the theoretical capability regarding instantaneous luminosity of the accelerator. [...]

Chaos indicators for nonlinear dynamics in circular particle accelerators / Montanari, C.E. (Manchester U. ; CERN) ; Appleby, R.B. (Manchester U.) ; Bazzani, A. (Bologna U. ; INFN, Bologna) ; Fornara, A. (Manchester U. ; CERN) ; Giovannozzi, M. (CERN) ; Redaelli, S. (CERN) ; Sterbini, G. (CERN) ; Turchetti, G. (Bologna U.)
The understanding of non-linear effects in circular storage rings and colliders based on superconducting magnets is a key issue for the luminosity the beam lifetime optimisation. A detailed analysis of the multidimensional phase space requires a large computing effort when many variants of the magnetic lattice, representing the realisation of magnetic errors or configurations for performance optimisation, have to be considered. [...]

Measurement of the nonlinear diffusion of the proton beam halo at the CERN LHC / Montanari, C.E. (Manchester U. ; CERN ; Cockcroft Inst. Accel. Sci. Tech.) ; Appleby, R.B. (Manchester U.) ; Bazzani, A. (Bologna U. ; INFN, Bologna) ; Giovannozzi, M. (CERN) ; Hermes, P. (CERN) ; Poyet, A. (CERN) ; Redaelli, S. (CERN) ; Sterbini, G. (CERN)
In circular particle accelerators, storage rings, or colliders, mitigating beam losses is critical to ensuring optimal performance, particularly for rings that include superconducting magnets. A thorough understanding of beam-halo dynamics is essential for this purpose. [...]

Analysis of double-resonance crossing in adiabatic trapping phenomena for quasi-integrable area-preserving maps with time-dependent exciters / Bazzani, Armando (Bologna U. ; INFN, Bologna) ; Capoani, Federico (Bologna U. ; INFN, Bologna) ; Giovannozzi, Massimo (CERN)
In this paper, we analyze the adiabatic crossing of a resonance for Hamiltonian systems when a double-resonance condition is satisfied by the linear frequency at an elliptic fixed point. We discuss in detail the phase-space structure on a class of Hamiltonians and area-preserving maps with an elliptic fixed point in the presence of a time-dependent exciter. [...]

Recent measurements and analyses of the beam-halo dynamics at the CERN LHC using collimator scans / Montanari, C E (Bologna U. ; CERN) ; Bazzani, A (Bologna U.) ; Giovannozzi, M (CERN) ; Hermes, P (CERN) ; Redaelli, S (CERN)
Controlling beam losses is of paramount importance in superconducting particle accelerators, mainly for ensuring optimal machine performance and an efficient operation. Models based on global diffusion processes, in which the form of the diffusion coefficient is the stability-time estimate of the Nekhoroshev theorem, have been studied and proposed to investigate the beam-halo dynamics.

Modelling the experimental data for long-range beam-beam wire compensators at the CERN LHC with diffusive models / Montanari, C E (Bologna U. ; CERN) ; Bazzani, A (Bologna U.) ; Giovannozzi, M (CERN) ; Poyet, A (CERN) ; Sterbini, G (CERN)
Current-carrying wires have long been proposed as measures to mitigate beam-beam effects. Dedicated hardware has been installed at CERN Large Hadron Collider (LHC) and experimental sessions have been organised to study the beam dynamics in the presence of the wire compensators. [...]

Numerical simulations of transverse nonlinear beam manipulations at the CERN PS / Capoani, F (Bologna U. ; CERN) ; Bazzani, A (Bologna U.) ; Giovannozzi, M (CERN)
A new set of nonlinear beam manipulations have been recently proposed, with the goal of extending the transverse beam splitting that is routinely used at the CERN PS to deliver beam to the SPS for fixed-target physics. Using a simple Hamiltonian model, it has been shown how the transverse emittances can be shared by crossing a two-dimensional nonlinear resonance. [...]

Analysis of a double-resonance crossing for beam splitting / Capoani, F (Bologna U. ; CERN) ; Bazzani, A (Bologna U.) ; Giovannozzi, M (CERN)
Beam splitting can be performed by adiabatic crossing of a given one-dimensional non-linear resonance. This process is routinely used at the CERN PS to deliver the proton beam to the SPS fixed-target physics. [...]

Performance analysis of indicators of chaos for nonlinear dynamical systems / Bazzani, A. (Bologna U. ; INFN, Bologna) ; Giovannozzi, M. (CERN) ; Montanari, C.E. (Bologna U. ; INFN, Bologna ; CERN) ; Turchetti, G. (Bologna U. ; INFN, Bologna)
The efficient detection of chaotic behavior in orbits of a complex dynamical system is an active domain of research. Several indicators have been proposed in the past, and new ones have recently been developed in view of improving the performance of chaos detection by means of numerical simulations. [...]
