Abstract

Radiation start-up is important in the simulation of virtually all free-electron laser (FEL) configurations. We discuss two different shot noise models that are implemented in both 1-D wiggler-averaged (PERSEO) and non-wiggler-averaged (MEDUSA1D) simulation codes, and a 3-D, non-wiggler-averaged (MEDUSA) formulation. Three-dimensional correction factors have been included in the MEDUSA1D and PERSEO, and all three codes are in remarkable agreement on the fundamental and harmonics.
