Simulations of Xray Sources from Xray Tubes to van-der-Waals Materials

I plan to present simulations of several xray sources. These sources include an xray tube, an undulator and free electrons in van-der-Waals materials. The xray tube and undulator are simulated in Geant4. The trajectories of the free electrons in the van-der-Waals materials are simulated by first calculating the electron density in the van-der-Waals materials using density functional theory.
