Beam Lifetime Studies
The study of nonlinear and long-term beam dynamics using codes such as BETACOOL, OPERA-3D, and MAD-X is needed to explain the physical effects in a whole class of low energy storage rings.
The Group have been investigating the performance of rings, such as ELENA and the USR, by means of beam dynamic simulations for different operation modes. This includes modelling all relevant physics phenomena for this kind of machine, e.g. Intra-Beam-Scattering (IBS), scattering on the residual gas and interaction with the electron cooler. This allows us to study lifetime and stability of the beam, as well as calculate the dynamic aperture of the machine under realistic assumptions.
