Online models for X-ray Beamlines

We present recent work on online models of x-ray optics for synchrotron light sources. An online model, or digital twin is a representation of the machine and corresponding physical process that may be updated based on diagnostic measurements. Working with the Tender Energy X-ray Absorption Spectroscopy (TES) beamline at the NSLS-II light source facility, we are pushing the state of the art in this domain by (1) Creation of simplified fast models for partially coherent radiation, (2) Development of software to interface with these models, and (3) Development of algorithms to take measured intensity data along with information about beamline set-up and build an accurate online model. The intent is to use this work as a prototype to apply to other x-ray beamlines at NSLS-II and other facilities to allow for faster mirror alignment procedures and better understanding of the beamline. We present progress along with a future outlook for this work.
