High field septum magnet using a superconducting shield for the Future Circular Collider / Dániel, Barna (Wigner Research Centre for Physics)
A zero-field cooled superconducting shield is proposed to realize a high-field (3–4 T) septum magnet for the Future Circular Collider hadron-hadron (FCC-hh) ring. Three planned prototypes using different materials and technical solutions are presented, which will be used to evaluate the feasibility of this idea as a part of the FCC study. [...]

Examination of Beryllium Under Intense High Energy Proton Beam at CERN's HiRadMat Facility / Ammigan, K. (Fermilab) ; Hartsell, B. (Fermilab) ; Hurh, P. (Fermilab) ; Zwaska, R. (Fermilab) ; Atherton, A. (Rutherford) ; Caretta, O. (Rutherford) ; Davenne,T. (Rutherford) ; Densham, C. (Rutherford) ; Fitton, M. (Rutherford) ; Loveridge, P. (Rutherford) et al.
Beryllium is extensively used in various accelerator beam lines and target facilities as material for beam win- dows, and to a lesser extent, as secondary particle produc- tion targets. With increasing beam intensities of future ac- celerator facilities, it is critical to understand the response of beryllium under extreme conditions to avoid compro- mising particle production efficiency by limiting beam pa- rameters.

Angular-Momentum Evolution in Laser-Plasma Accelerators / Thaury, Cédric (Laboratoire d'Optique Appliquée) ; Guillaume, Emilien (Laboratoire d'Optique Appliquée) ; Corde, Sébastien (Laboratoire d'Optique Appliquée) ; Lehe, Rémi (Laboratoire d'Optique Appliquée) ; Le Bouteiller, Madeleine (Laboratoire d'Optique Appliquée) ; Ta Phuoc, Kim (Laboratoire d'Optique Appliquée) ; Davoine, Xavier (CEA, DAM, DIF, France) ; Rax, J. M. (Laboratoire d'Optique Appliquée) ; Rousse, Antoine (Laboratoire d'Optique Appliquée) ; Malka, Victor (Laboratoire d'Optique Appliquée)
The transverse properties of an electron beam are characterized by two quantities, the emittance which indicates the electron beam extent in the phase space and the angular momentum which allows for non-planar electron trajectories. Whereas the emittance of electron beams produced in laserplasma accelerator has been measured in several experiments, their angular momentum has been scarcely studied. [...]

Upgrade of the CERN SPS Extraction Protection Elements TPS / Borburgh, Jan (CERN) ; Balhan, Bruno (CERN) ; Barnes, Michael (CERN) ; Baud, Cedric (CERN) ; Fraser, Matthew (CERN) ; Kain, Verena (CERN) ; Maciariello, Fausto (CERN) ; Steele, Genevieve (CERN) ; Velotti, Francesco (CERN)
In 2006 the protection devices upstream of the septa in both extraction channels of the CERN SPS to the LHC were installed. Since then, new beam parameters have been proposed for the SPS beam towards the LHC in the framework of the LIU project. [...]

The effect of space charge on bunches stored for long term in a nonlinear lattice can be severe for beam survival. This may be the case in projects as SIS100 at GSI or LIU at CERN. [...]

Mitigation of Numerical Noise for Beam Loss Simulations : Proc. HB2016 Malmo, Sweden / Kesting, Frederik (U. Frankfurt) ; Franchetti, Giuliano (GSI)
Numerical noise emerges in self-consistent simulations of charged particles, and its mitigation is investigated since the first numerical studies in plasma physics. In accelerator physics, recent studies find an artificial diffusion of the particle beam due to numerical noise in particle-in-cell tracking, which is of particular importance for high intensity machines with a long storage time, as the SIS100 at FAIR or in context of the LIU upgrade at CERN.
