Electromagnetic simulations for the design of a superconducting REBa$_2$Cu$_3$O$_{7-x}$–Cu coated beam screen for the CERN future circular hadron collider / Telles, Guilherme T (Barcelona, Autonoma U.) ; Calatroni, Sergio (CERN) ; Giovannozzi, Massimo (CERN) ; Granados, Xavier (Barcelona, Autonoma U.) ; Puig, Teresa (Barcelona, Autonoma U.) ; Gutierrez, Joffre (Barcelona, Autonoma U.)
In particle accelerators, the beam screen is the device responsible for shielding the superconducting magnets from the synchrotron radiation emitted by the orbiting charged particles. It is crucial to have a low value of the coupling impedance between the beam and the surrounding beam screen to avoid collective instabilities of the charged beams [...]

Analytic derivative of orbit response matrix and dispersion with thick error sources and thick steerers implemented in python / Franchi, Andrea (ESRF, Grenoble) ; Liuzzo, Simone (ESRF, Grenoble) ; Martí, Zeus (ESRF, Grenoble)
While large circular colliders rely upon analysis of turn-by-turn beam trajectory data to infer and correct magnetic lattice imperfection and beam optics parameters, historically storage-ring based light sources have been exploiting orbit distortion, via the orbit response matrix. However, even large collider usually benefit of the orbit analysis during the design phase, in order to evaluate and define tolerances, correction layouts and expected performances. [...]

Landau Damping / Buffat, Xavier (CERN)
Landau damping is a key mechanism to preserve the stability of particle beams under the influence of various collective forces that would otherwise spoil its quality through beam instabilities. [...]

Shutter-type multi-point optical alignment using a Structured Laser Beam in vacuum / Niewiem, Witold Grzegorz (ETH, Zurich (main) ; CERN) ; Figura, Sebastian Antoni (CERN) ; Dusek, Martin (Liberec Tech. U. ; CERN) ; Mergelkuhl, Dirk (CERN) ; Gayde, Jean-Christophe (CERN) ; Wieser, Andreas (ETH, Zurich (main))
This paper presents an alignment concept employing a Structured Laser Beam (SLB) for offset measurements over a 140 m distance. The prototype consists of an SLB generator and three measurement stations within a vacuum system. [...]

Simulation of plasma accelerators with the Particle-In-Cell method / Vay, J L (LBNL, Berkeley)
We present the standard electromagnetic Particle-in-Cell method, starting from the discrete approximation of derivatives on a uniform grid. The application to second-order, centered, finite-difference discretization of the equations of motion and of Maxwells equations is then described in one dimension, followed by two and three dimensions.
