The LHC Transverse Coupled-Bunch Instability

Nicolas Frank Mounet

In this thesis, the problem of the transverse coupled-bunch instabilities created by the Large Hadron Collider (LHC) beam-coupling impedance, that can possibly limit the machine operation, is addressed thanks to several new theories and tools. A rather com ...

IMPEDANCE EFFECTS IN THE CLIC DAMPING RINGS

Nicolas Frank Mounet, Eirini Koukovini Platia, Benoît Salvant, Giovanni Rumolo

Due to the unprecedented brilliance of the beams, the performance of the Compact Linear Collider (CLIC) damping rings (DR) is affected by collective effects. Single bunch instability thresholds based on a broad-band resonator model and the associated coher ...

Update of the SPS Impedance Model

Nicolas Frank Mounet, Carlo Zannini, Benoît Salvant

The beam coupling impedance of the CERN SPS is expected to be one of the limitations to an intensity upgrade of the LHC complex. In order to be able to reduce the SPS impedance, its main contributors need to be identified. An impedance model for the SPS ha ...

ELECTROMAGNETIC SIMULATIONS OF SIMPLE MODELS OF FERRITE LOADED KICKERS

Nicolas Frank Mounet, Carlo Zannini, Benoît Salvant

The kickers are major contributors to the CERN SPS beam coupling impedance. As such, they may represent a limitation to increasing the SPS bunch current in the frame of an intensity upgrade of the LHC. In this paper, CST Particle Studio time domain electro ...

IMPEDANCES OF AN INFINITELY LONG AND AXISYMMETRIC MULTILAYER BEAM PIPE: MATRIX FORMALISM AND MULTIMODE ANALYSIS

Nicolas Frank Mounet

Using B. Zotter’s formalism, we present here a novel, efficient and exact matrix method for the field matching determination of the electromagnetic field components created by an offset point charge travelling at any speed in an infinitely long circular mu ...

THE SIX ELECTROMAGNETIC FIELD COMPONENTS AT LOW FREQUENCY IN AN AXISYMMETRIC INFINITELY THICK SINGLE-LAYER RESISTIVE BEAM PIPE

Nicolas Frank Mounet

In this study B. Zotter’s formalism is applied to a circular infinitely long beam pipe made of a conductor of infinite thickness where an offset point-charge travels at any given speed. Simple formulae are found for the impedances and electromagnetic field ...

This paper aims at giving a derivation of the six electromagnetic field components created by an offset point charge travelling at any speed in a flat chamber, i.e. a two dimensional structure consisting of two infinite parallel plates surrounding a vacuum ...

MULTI-BUNCH EFFECT OF RESISTIVEWALL IN THE CLIC BDS

Nicolas Frank Mounet, Raphaël Mutzner

Wake fields in the CLIC Beam Delivery System (BDS) can cause severe single or multi-bunch effects leading to luminosity loss. The main contributors in the BDS are geometric and resistive wall wake fields of the collimators and resistive wall wakes of the b ...

The SPS kickers are major contributors to the SPS transverse beam coupling impedance. The current ”flat chamber” impedance model for a kicker is obtained by applying form factors to the theoretical impedance of an axisymmetric ferrite beam pipe. This model ...

GENERALIZED FORM FACTORS FOR THE BEAM COUPLING IMPEDANCES IN A FLAT CHAMBER

Nicolas Frank Mounet

The exact formalism from B. Zotter to compute beam coupling impedances has been fully developed only in the case of an infinitely long circular beam pipe. For other two dimensional geometries, some form factors are known only in the ultrarelativistic case ...
