Postdoctoral Research Associate in Radiation-Resilient Scintillator Materials for Fusion Diagnostics
Los Alamos National LaboratoryWhat You Will Do The Materials Science and Technology Structure / Property Relations group (MST-8) at Los Alamos National Laboratory seeks a highly motivated Postdoctoral Research Associate to develop next-generation radiation-resilient scintillator materials for fusion energy and national security applications. The successful candidate will work at the interface of experimental materials science and computational modeling to understand how radiation-induced defects form, evolve, and degrade scintillator performance under extreme environments. The project combines controlled ion irradiation experiments, advanced structural and spectroscopic characterization, atomistic electronic structure calculations, and multiscale defect evolution modeling to establish predictive structure-property relationships for scintillator degradation. The ultimate goal is to enable the design of radiation-hardened scintillators with improved lifetime and performance for fusion diagnostics and other radiation detection technologies. The postdoctoral researcher will work closely with experimentalists and computational scientists across Los Alamos National Laboratory and will have opportunities to contribute to high-impact publications, present research at international conferences, and participate in multidisciplinary collaborations supporting DOE Office of Science and NNSA mission areas. What You Need Minimum Job Requirements: Demonstrated experience with Czochralski single-crystal growth and/or other single-crystal growth techniques. Experience with solid-state synthesis, ceramic processing, and densification of oxide materials. Experience with structural characterization techniques, including X-ray diffraction (XRD), single crystal diffraction. Experience determining the optical and electronic properties of materials, including band gap measurements using UV-Vis spectroscopy, photoluminescence (PL), photoluminescence excitation (PLE) spectroscopy or related techniques. Excellent communication and writing skills, as evidenced by publications, cover letter and interview. Demonstrated ability to work creatively and independently as well as learn and collaborate with experts as a part of a multi-disciplinary team. Education/Experience : Ph.D. in Chemistry, Physics, Materials Science, Chemical Engineering, or a related field completed within the last five years. Desired Qualifications: In addition to the minimum requirements, the following qualifications are desired, and preference will be given to candidates satisfying (at least one) of them: Familiarity with materials characterization techniques such as electron microscopy, X-ray absorption spectroscopy, Raman spectroscopy, or optical spectroscopy. Experience in synchrotron or neutron scattering techniques. Experience in time-resolved optical spectroscopy or scintillation measurements. Experience in radiation effects in materials or radiation damage studies particularly using ion beams. Experience in defect characterizations using positron annihilation spectroscopy and/or Rutherford backscattering spectrometry in channeling configurations. Knowledge of scintillator materials, phosphors, optical ceramics, or rare-earth-doped materials. Experience in density functional theory (DFT), atomistic simulations, or multiscale modeling. Experience in computer programming using modern computing languages. Programming skills in Python and/or scientific computing environments. Demonstrated ability to work independently and with minimum supervision. Willingness to work productively on multiple projects. Work Location: The work location for this position is onsite and located in Los Alamos, NM. All work locations are at the discretion of management.
