First Analysis of the Space Charge Effects on a Third Order Coupled Resonance : Proc. HB2016 Malmo, Sweden / Franchetti, Giuliano (GSI) ; Gilardoni, Simone (CERN) ; Huschauer, Alexander (CERN) ; Schmidt, Frank (CERN) ; Wasef, Raymond (CERN)
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.

Higgs Factory Concepts : Proc. eeFACT2016 Daresbury, UK, October 2016 / Zimmermann, Frank (CERN)
Designs for future high-energy circular electron-positron colliders are based on both established and novel concepts. An appropriate design will enable these facilities to serve not only as "Higgs factories", but also as Z, W and top factories, and, in addition, to become a possible first step to a higher-energy hadron collider..

A Stochastic Approach in Uncertainty Budgeting for Accelerator Pre-Alignment–Study for The Clic Project / Doytchinov, Iordan Petrov (CERN)
A new strategy for uncertainty budgeting estimation following the International Standard (GUM - Supplement 1) is proposed as alternative to current classical methods of error budgeting applied in the domain of accelerator components. This strategy applies stochastic modelling on the uncertainty contributing factors for providing probability density function as quantification of pre-alignment measurements uncertainty. [...]
