Senior Source Scientist

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, targets, housings, and diagnostic instrumentation.


* Quantitatively characterize beam properties, X-ray spectra, flux, temporal stability, and thermal behavior.


* Collaborate closely with mechanical, electrical, software, and system engineering teams to ensure compatibility and readiness for system level integration.

System Level Integration & Collaboration


* Work with imaging system architects to ensure alignment between source performance and overall imaging requirements (resolution, contrast, speed).


* Support integration into instrument platforms, including vacuum interfaces, alignment tolerances, power electronics, and control algorithms.


* Contribute to development of source health monitoring, control loops, and advanced source stabilization strategies.

Scientific Leadership & Project Management


* Own research projects from conception through execution, including planning, risk assessment, and reporting.


* Mentor junior engineers, interns, and visiting researchers in electron optics and X-ray source physics.


* Foster innovation culture within ADD by identifying emerging technologies and strategic opportunities.



* PhD or Master’s degree in Physics, Electrical Engineering, Materials Science, or a related field with specialization in electron optics, charged‑particle systems, vacuum devices, or radiation physics.


* Demonstrated experience designing or modeling electron guns, electron‑optical lenses, or charged‑particle transport systems.


* Experience with X‑ray generation, X‑ray targets, high‑vacuum systems, or miniaturized radiation sources strongly preferred.

Experience in X‑ray tomography systems preferred.
