Description
Crab cavities have been proposed at a number of particle colliders to increase the luminosity in the presence of a crossing angle, including the LHC upgrade, ILC and CLIC colliders. These RF devices rotate the incoming bunches prior to collision in order to provide a head-on collision. However if the phase and amplitude is sufficiently unstable the crab cavities can cause a decrease rather than an increase of luminosity. In addition wake field instabilities can also reduce the luminosity of the collider. The effects of these instabilities as well as cavity alignment on the peak luminosity has been studied using the beam tracking code PLACET combined with the code GUINEA-PIG to simulate collisions, as well as using analytical techniques to calculate the variations in luminosity.
