We are seeking a Member of the Technical Staff to collaborate on the development, characterization, calibration, and data interpretation of neutron diagnostics fielded at the Z machine to support Inertial Confinement Fusion experiments\. This individual will be part of a team of scientists and technologists focused on fielding existing, and developing new, fusion neutron diagnostics\. This individual will have the role of a Responsible Scientist for one or more neutron diagnostics\. In this role, this individual will take personal responsibility for the diagnostic development, maintenance, data interpretation, and long\-term scientific mission needs\. This individual will be collaborating with the broader science community in the Sandia Pulsed Power Sciences Center and at other national laboratories and universities\. The work involves diagnostic development, assembly, testing, and calibration in light labs and at other facilities such as the Ion Beam Laboratory at Sandia\.

Key functions of this role include, but are not limited to:

+ Collaborate with the international high\-energy\-density \(HED\) physics community, and represent the research and development in the organization through publications in scientific journals and presentations at conferences

+ Interface with scientists, engineers, and technicians to coordinate experimental activities in the Inertial Confinement Fusion program

+ Analyze data using theoretical, numerical, and empirical models

+ Model neutron scattering effects in the Z machine environment using numerical models to understand and improve neutron diagnostic data quality and stand up new diagnostic capabilities

+ Support Sandia staff and work independently and proactively on neutron diagnostic development

+ Travel to facilities such as NStec\-Las Vegas, Nevada Test Site, National Ignition Facility, Omega Laser Facility at the University of Rochester


+ BS and PhD in Physics, Nuclear Engineering, or related field

+ Experience with numerical analysis, including computer language skills, data reduction, uncertainty analysis and scientific comparison of experiment and theory/modeling

+ One or more co\-authored publications in a related area of research, such as nuclear physics, nuclear reactor technology, experimental or theoretical/computation for neutron environments, neutron or x\-ray radiation sources or diagnostics, HED physics, or plasma physics


+ Five years experience in HED physics or fusion neutron diagnostics

+ Strong record of publications in a related area of research, including first\-authored publications

+ Knowledge of z\-pinch or dense plasma focus design, operation, and diagnosis

+ Experience with fielding and characterizing neutron activation detectors, neutron time\-of\-flight detectors, or neutron imaging systems

+ Experience with numerical modeling of neutron environments for experimental diagnostics design and interpretation of data particularly coupling three\-dimensional modeling of neutron scattering and absorption \(e\.g\., MCNP or Geant\) to physical models

+ Experience fielding or analyzing data from experiments or diagnostics at a major pulsed power or high\-energy\-density physics facility

+ Experience performing gamma\-ray spectroscopy using high\-purity germanium, sodium\-iodide, or other similar detectors

+ Experience working with radioactive sources, radiation generating devices and diagnostic calibration components

+ Experience performing radiological work, and interacting with radiological support groups, for example in coordinating the fielding and analyzing of TLDs or CR\-39 dosimetry detectors

+ Experience processing and interpreting data from nuclear track detectors such as CR\-39

+ Experience in designing, building and operating high\-voltage detector electronics and data acquisition systems including electronic circuits, proper cable plants, computer control interfaces, and data acquisition systems including digitizers and pulse generators

+ Strong electro\-mechanical skills to perform both laboratory calibration and experimental fielding of diagnostics equipment such as nuclear electronics, vacuum chambers, gamma\-ray detectors, neutron activation detectors, and data acquisition systems

+ Experience leading experiments in a large team environment

+ Excellent verbal, written, planning, and interpersonal skills conducive to working as a part of a large team

+ Highly self\-motivated, adaptable to change, and an excellent work ethic suited to making rapid progress through independently directed work

+ Ability to develop collaborations with external organizations

Department Description:

The Radiation and Fusion Diagnostics Department \(1676\) researches, develops and fields state\-of\-the\-art diagnostic systems for measuring conditions created in high energy density science experiments on the Z Machine\. The department is composed of a multidisciplinary team of scientists and technologists that work together in a collaborative environment to develop and field temporally\-, spatially\-, and/or spectrally\-resolving diagnostics with an emphasis on instruments that measure X\-ray and Neutron emission\. These measurements can have nanosecond to 100 picosecond time scales and tens of microns of spatial resolution\. The departments activities include fielding of several neutron activation materials for measuring neutron yields, several neutron time\-of\-flight detectors for inferring ion temperature and other information from fusion plasmas, and a new one\-dimensional neutron imager\. The department also supports a large suite of X\-ray fluence measurements to characterize X\-ray outputs and soft and warm X\-ray imaging and spectroscopy to characterize source performance\. In addition, the team performs calibration and characterization of the detectors and critical diagnostic component \(e\.g\., crystal, filter, slit, pinhole, and PMT\) responses for neutron and X\-ray diagnostics\. Also core to the departments mission is new diagnostic development such as neutron imaging, fusion burn history, and high\-resolution time\-gated X\-ray imaging\.
