TREDI SIMULATIONS FOR HIGH-BRILLIANCE PHOTO-INJECTORS

The TREDI Monte-Carlo program is briefly described, devoting some emphasis to the Lienard-Wiechert potentials approach followed to account for self-fields effects and the covariant technique devised to achieve regularization of electro-magnetic fields. Some guidelines to the choice of the correct parameters to be used in the simulation are also summarily sketched. The predictions obtained for the reference workpoint of the space-charge compensated SPARC project photo-injector are finally compared to those from other well-established simulation codes.
