Cap-Exempt H-1B Position — No lottery required
**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 with emphasis on achieving controlled neutron fluxes for in situ irradiation experiments. The postdoctoral researcher will work as part of a multidisciplinary team involving ion beam systems, neutron target design, accelerator operations, scanning electron microscopy, neutron diagnostics, software control, and experiment safety authorization. The position will include hands-on experimental work, system integration, data analysis, documentation, and reporting. **What You Need** **Minimum Job Requirements:** - Demonstrated experimental experience with ion sources, ion beamlines, accelerator facilities, ion source test stands, or related charged-particle beam systems. - Demonstrated experience using beam diagnostics, which may include Faraday cups, beam current monitors, profile monitors, scintillators, 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. **Desired Qualifications:** - 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
