- The spectral, spatial and polarization characteristics of the radiation in the near field and/or far field approximation produced by a relativistic electron beam traveling through an arbitrary magnetic field. The magnetic field data is either created by a macro or can be read from a file. The computed wavefront of the radiation can be propagated through drift spaces, lenses (Mirror, Refractive, Fresnel...), apertures or arbitrary 2D phase shifting elements.
- Fast numerical algorithms are used for bending magnets radiation and periodic field Insertion devices such as linear, ellipsoidal, figure-8, tapered and optical klystron type of undulators or wigglers. The computation includes electron beam emittance and energy spread.
- The pre and post processing is made in the Igor Pro (low cost) graphing and analyzing software. All computations are driven by dialog box and/or command lines. Command lines can easily be grouped into a user defined macro to parametrize and/or automate a sequence of computation. The result can be visualized in linear, contour, image and surface plots. Publication quality transparencies can be produced from within Igor. Extension and/or customization is easily done using either the powerful Igor macro language or using C , C++ or Fortran.
