20.500.12556/RUL-158312 Numerical simulations of temperature loads on multilayer Laue lenses We present numerical simulations of the heat loads on novel diffractive X-ray optics, known as multilayer Laue lenses, exposed to high-intensity X-ray beams produced by an X-ray free electron laser (XFEL). These lenses can be used to focus XFEL beams to nanometer spots. The temperature distribution within the lens and temperature evolution as a function of incident pulse frequencies were calculated for two different lens geometries and several material pairs and material ratios of the MLLs. Simulations considered the special pulse structure of European XFEL with X-rays being delivered in pulse trains. After defining the geometric model, computational grid, material properties, and boundary conditions, a grid sensitivity study was carried out. We solved the transient heat energy transport equation in solids for mixed boundary conditions. The results of these simulations will help select materials and lens geometry for future XFEL experiments. numerical simulations heat transfer x-ray free-electron lasers multilayer Laue lens numerične simulacije prenos toplote rentgenski laserji s prostimi elektroni večplastna leča Laue true false true Angleški jezik Slovenski jezik Neznano 2024-06-04 14:11:24 2024-06-04 14:11:27 2025-04-21 11:47:10 0000-00-00 00:00:00 2024 0 0 6 str.
