Description :
Job_Summary General Atomics (GA), and its affiliated companies, is one of the world s leading resources for high-technology systems development ranging from the nuclear fuel cycle to remotely piloted aircraft, airborne sensors, and advanced electric, electronic, wireless and laser technologies. We recognize and appreciate the value and contributions of individuals with diverse backgrounds and experiences and welcome all qualified individuals to apply. The DIII-D National Fusion Facility is the U.S. s principal magnetically confined fusion research facility, focusing om the exciting science of the burning plasma state and its control in preparation for ITER, and developing the path to self-driven steady-state operation for future fusion reactors. It has a strong focus on underlying science, and the application of this to improve fusion performance. The DIII-D program is expanding its scientific output and has need for a number of scientists in key areas. The goal is to pioneer advances in fusion and plasma science, and discover new approaches to make fusion energy a reality. DIII-D scientists are world leading and expected to exhibit very high capabilities in understanding complex plasma physics, developing advanced diagnostics, models or control techniques, and showing a high degree of initiative in a team environment. We are always interested in talented individuals in a range of areas. This year there are particular opportunities in the following areas. A range of experience levels will be considered. Key_Roles,_Duties_&_Responsibilities * Divertor optimization scientist, focusing on understanding the interplay between drift effects and divertor closure, and integrated data analysis of detached plasmas. The jobholder will also engage in development of state-of-the-art diagnostics for advanced divertor studies and associated analysis to support model validation. Experience in spectroscopy is desirable. * Plasma control science to develop advanced control solutions for tokamak plasmas on DIII-D, with opportunities to engage in international tokamaks. Activities include software development, control simulation, participating in and leading experiments, presenting and publishing results. * Senior plasma physics operator, experienced in leading complex tokamak experiment programs, organizing a team, and understanding the technical challenges and systems of a working tokamak. * Plasma scenario development expert, with knowledge of underlying and interconnected challenges faced in reaching high performance tokamak operation, and particularly issues of plasma stability. Activities include proposing and leading experiments, analysis, simulations, presenting and publishing results. * Integrated modeling expert to analyze behavior in tokamak plasmas, using state of the art simulations to interpret phenomena and test physics concepts, and design new approaches or facility upgrades. Contribute to simulation tool development and provision to the wider team. * Radiofrequency physics experts for heating and current drive in tokamaks to understand detailed physical mechanisms and develop innovative RF approaches through engagement with hardware development, measurement, analysis, simulation, and experiments, including application and optimization of high performance plasma scenarios. * Plasma stability and 3D response scientist to focus on control of edge localized modes and related measurement and physics of 3D magnetic perturbation techniques. Work will involve an appropriate mix of leading experiments, analyzing data, simulation and magnetic diagnostic support. There are also opportunities to work with the DIII-D disruption mitigation team and international collaborators to test and understand the physics of plasma quench techniques and associated plasma evolution. * Energetic particle scientist, to understand the physics of fusion self- heating and associated driven instabilities through experiments, analysis and development of innovative diagnostics. The jobholder will also connect the confinement of fast ions in DIII-D to performance improvement and control of advanced scenarios. * Programmer and analyst for diagnostic systems including charge exchange recombination measurements. This is a non-scientific role (minimum requirement Bachelor s degree in relevant field), with focus on software and analysis support, and provision of excellent diagnostic capability. All positions will also involve: * Scientific leadership opportunities. * Work in the multidisciplinary team environment of the DIII-D tokamak. * Opportunities to work on various other national or international facilities. * Participation in experimental operation and support of DIII-D. * Publishing in recognized scientific journals and presenting work at national and international levels. * Perform other duties as assigned or required. Job_Qualifications * Typically requires a Bachelors degree, Masters degree or PhD in a scientific or related technical field and progressively complex scientific experience as follows; six or more years experience with a Bachelors degree, four or more years experience with a Masters degree, and two or more with a PhD. * Must possess the ability to independently (1) understand new concepts quickly; (2) apply them accurately throughout an evolving environment; (3) organize, schedule, and coordinate work phases; and, (4) determine the appropriate approach at the task level or, with assistance, at the project level to provide solutions to a range of complex problems. * Must have strong communication, computer, documentation, presentation, and interpersonal skills, ability to work independently and as part of a team; able to perform complex tasks in one scientific area; and, lead a team of less experienced professional employees on semi-routine tasks. * Facility in moving rapidly from one task area to another, and ability to work extended hours and travel as required. * Ability to communicate effectively with the scientific and engineering communities of DIII-D and collaborators, including written and oral technical presentations. * Willingness to adjust working hours in accordance with the schedules and needs of the Fusion Division.
