RAYX is a simulation tool for beamlines at electron storage rings. It traces synchrotron radiation through a series of mirrors, gratings and more and provides the user with helpful insights, how a given beamline performs.
This source is used for simulating a Undulator source in a very simple way: it is a point source whose quantities (source size and divergence) are calculated from very simple assumptions based on real undulator source calaculations (see RAY-UI).
In SHADOW such a source is called "Gaussian Undulator", we could also call it that and check in this course whether we really simulate a Gaussian beam with our point source, see the following publication:
