Analyzing Plasma-Crystal Interactions Using Bragg's Law*

Great physicists, including M. von Laue, W. Friedrich, P. Ewald, and P. Knipping, investigated the interaction between light and crystalline materials. By directing collimated X-rays at crystals, they found that X-rays with wavelengths around 1 Å were diffracted by solids with ordered lattice structures, capturing the first X-ray diffraction photograph. This discovery led Lawrence Bragg to develop Bragg's Law, which explains how X-rays reflect off crystalline surfaces. Subsequent experiments validated this law and the nature of X-ray diffraction, ultimately leading to the development of X-ray spectroscopy.¹ In this study, we present a coding simulation for analyzing the interaction of plasma with crystal structures. The simulation allows users to input source points that initiate rays impacting predefined crystal points, resulting in reflection rays. The angle of incidence is calculated, facilitating the determination of reflection angles based on Bragg’s Law. The distances between the source points and reflection rays are computed. Additionally, the energy associated with the incident angle is derived, and the corresponding distance is compared in a dispersion curve. This simulation provides a tool for studying plasma behavior in crystal environments.
