Transverse beam cavity interaction. Part I: Short range forces

Longitudinal and transverse coupling in infrared gold nanoantenna arrays: long range versus short range interaction regimes.

Interaction between micrometer-long nanoantennas within an array considerably modifies the plasmonic resonant behaviour; for fundamental resonances in the infrared already at micrometer distances. In order to get systematic knowledge on the relationship between infrared plasmonic resonances and separation distances dx and dy in longitudinal and transverse direction, respectively, we experimenta...

Transverse Deflections in a Cavity to the Short-range Longitudinal Wake

This note do consider a conventiona conversion target and t Since the length of the concurrent pressure pu Due K. L. Linear Collider Collaboration Tech Notes cuments a set of expressions used to explore the issue of whether or not it is reasonable to l positron source for a Tesla formatted beam. The critical issue is that of energy deposition in the he comparison of the induced stress with the ...

Deflecting Forces for the Case of Multi Mode Beam - Rf Cavity Interaction in Linear Accelerators

Abstract The formulae for the deflecting rf forces have been derived for the train of charged bunches, traversing a rf cavity. These forces originate from the deflection action of non symmetrical modes excited by the misalined bunches, the infinite set of the cavity eigen modes being taken into account. Various dependencies are explored, including the effect of "mode saturation" and non lineari...

Nonequilibrium wetting transitions with short range forces.

We analyze within mean-field theory as well as numerically a Kardar-Parisi-Zhang equation that describes nonequilibrium wetting. Both complete and critical wettitng transitions were found and characterized in detail. For one-dimensional substrates the critical weting temperature is depressed by fluctuations. In addition, we have investigated a region in the space of parameters (temperature and ...
