In a circular accelerator, a horizontal-vertical coupling can occur as a purely geometrical effect, in the absence of any coupling device (skew-quadrupole magnets, etc.). The coupling between horizontal and vertical coordinates (and momenta) is repre

The possible use of open cell conductive foams in high synchrotron radiation particle accelerators is considered. Available materials and modeling tools are reviewed, potential pros and cons are discussed, and preliminary conclusions are drawn.

Molecular gas desorption from the beam-pipe wall due to synchrotron radiation has been a major solved issue in the design of the LHC [1]. Nuclear scattering in the desorbed gas may limit the beam luminositity lifetime, and produce high energy protons

Luminosity is one of the key concepts for accelerator design. When the design target is a narrow energy peak, the (collision) energy resolution becomes more relevant. In this paper fairly accurate expressions for luminosity and energy resolution base

We introduce an equivalent wall impedance to describe the electromagnetic boundary conditions at perforated pipe walls. The new impedance boundary condition, together with our general formulae for computing longitudinal and transverse beam coupling i

Effects of a large dispersion at the interaction point are studied within the linear approximation. Several effects exist on the synchrotron motion, including the synchrotron tune shift, the bunch lengthening, and energy spread modification, which mi

Using a simple wake function, it is shown that the equilibrium bunch length in electron storage rings with localized wake can have a cusp-catastrophe behavior. Contrary to the results of the conventional theory for a distributed wake force, the syste

The generation of a quasistationary electron cloud inside the beam pipe through beam-induced multipacting processes has become an area of intensive study. The analyses performed so far have been based on heavy computer simulations taking into account

The validity of the Gaussian approximation of the distribution function in the study of the equilibrium bunch length in electron storage rings is considered with specific reference to the inductive wake. The Gaussian approximation can be used to desc
