Job description

X-ray Source & Electron-Optics Design: - Design and model electron gun architectures (thermionic, field emission, or other advanced emitters) with emphasis on beam quality, focusing, brightness, and stability. - Develop electrostatic and magnetic lens systems, beam shaping elements, and electron-optical column architectures. - Perform charged particle trajectory simulations (e.g., using COMSOL, CST, SIMION, etc.) to optimize beam transport, spot size, and landing characteristics. - Design and evaluate target materials, geometries, and cooling strategies to optimize X-ray generation efficiency and spectral characteristics. Fundamental Electron–Target Interaction Research: - Model electron energy deposition, bremsstrahlung yield, characteristic line emission, and thermal/mechanical load in X-ray targets. - Investigate novel target concepts (rotating, liquid metal, multilayer, nanostructured, etc.) to enhance flux, brightness, and lifetime. - Develop experimental setups to characterize X-ray output, stability, and source degradation pathways. Prototype Development & Characterization: - Lead the build, testing, and iteration of source prototypes, including electron optical assemblies,...
