X-ray optics - Bragg deflection - Any example/package?

Hello,

I am trying to simulate the interaction between soft X-rays and an MPO detector, e.g. particularly Bragg deflection and grazing angle. By reminding that the X-ray optics are not pre-defined in GEANT4, does anyone know any example or package related to the X-ray optics, especially Bragg deflection in GEANT4? I would appreciate if anyone could share some information about it.

Thank you,

AIT

You could look at the new (in 11.2) G4XRayReflection class, and example usage in extended/electromagnetic/TestEm16.
