Ion Beam Experimental Postdoc

What You Will Do

MST‑8 is seeking a highly motivated Postdoctoral Research Associate to support the development of an ion‑beam‑driven neutron irradiation capability for materials and diagnostics applications. The successful candidate will contribute to the design, commissioning, calibration, and operation of a proton‑on‑lithium neutron source, emphasizing controlled neutron fluxes for in‑situ irradiation experiments. The role involves hands‑on experimental work, system integration, data analysis, documentation, and reporting within a multidisciplinary team that includes ion‑beam systems, neutron target design, accelerator operations, scanning electron microscopy, neutron diagnostics, software control, and experiment safety authorization.

• Demonstrated experimental experience with ion sources, ion beamlines, accelerator facilities, ion source test stands, or related charged‑particle beam systems.
• Experience using beam diagnostics such as Faraday cups, beam current monitors, profile monitors, scintilla tors, phosphor screens, emittance diagnostics, energy analyzers, or related instrumentation.
• Knowledge of ion‑beam interactions with targets, beam transport, accelerator operations, vacuum systems, high‑voltage systems, or beamline control systems.
• Ability to design, execute, document, and analyze complex experiments involving beam delivery, target response, radiation production, or diagnostic calibration.
• Demonstrated ability to meet technical milestones, project deliverables, and sponsor expectations in a research or development environment.

• Experience with accelerator‑based neutron production, especially proton‑on‑lithium or other light‑ion‑induced neutron reactions.
• Experience with lithium, lithium compounds, or other neutron production target materials, including target fabrication, thermal management, target degradation, or beam‑power handling.
• Experience measuring neutron flux, neutron spectra, or radiation fields using neutron detectors, activation foils, scintilla tors, proportional counters, Bonner spheres, or related diagnostics.
• Experience with radiation transport, activation, or detector‑response modeling using tools such as MCNP, GEANT4, PHITS, FLUKA, SRIM/TRIM, COMSOL, or similar software.
• Experience developing software for experimental control, data acquisition, instrument synchronization, or automation using Python, LabVIEW, EPICS, MATLAB, C/C++, or related tools.
• Experience with scanning electron microscopy, in‑situ microscopy, materials irradiation, radiation damage, polymers, energetic materials, or microstructural characterization.

Ph.D. in accelerator physics, nuclear engineering, experimental physics, materials science, mechanical engineering, electrical engineering, applied physics, or a closely related field.
