MLgrating: a program for simulating multilayer gratings for tender X‐ray applications

Multilayer gratings are increasingly popular optical elements at X‐ray beamlines, as they can provide much higher photon flux in the tender X‐ray range compared with traditional single‐layer coated gratings. While there are several proprietary software tools that provide the functionality to simulat...

Summary:Multilayer gratings are increasingly popular optical elements at X‐ray beamlines, as they can provide much higher photon flux in the tender X‐ray range compared with traditional single‐layer coated gratings. While there are several proprietary software tools that provide the functionality to simulate the efficiencies of such gratings, until now the X‐ray community has lacked an open‐source alternative. Here MLgrating is presented, a program for simulating the efficiencies of both multilayer gratings and single‐layer coated gratings for X‐ray applications. MLgrating is benchmarked by comparing its output with that of other software tools and plans are discussed for how the program could be extended in the future. MLgrating, a MATLAB program for simulating multilayer grating efficiencies, is presented.
