Evolution and resolution in FEL code CODCOM
Abstract
We describe inefficiencies of the quasi-fast Hankel transform method for optical source problems. Then we adopt the Gauss-Laguerre technique and describe how the finite representation determines its resolution. These results are summarized in a few formulas. Finally we describe transmission through an aperture with this technique.
