PPPL ITER and Tokamaks
Research and Laboratory
Princeton Plasma Physics Laboratory has an open position for a research staff
scientist at the DIII-D national fusion facility, located in San Diego, CA.
The candidate will employ 2-D and 3-D models of the edge plasma to understand
and optimize the effects of particle injection (impurities and hydrogenic
neutrals) on the dynamics of the pedestal, scrape-off layer and divertor. In
the near term, particular emphasis will be given to the study of low-Z
impurity powders to enhance radiation in the plasma boundary and mediate the
plasma-material interaction. The candidate will design, lead and model tokamak
experiments making use of actuators such as gas and solid material injection
into tokamak plasmas to determine the effectiveness of innovative approaches
to overcoming the core-edge integration challenge, including effective edge
power dissipation in high confinement plasmas.
The candidate will also develop a program of research to model and understand
the poloidal distribution of neutrals and the effect of such neutrals on
confinement and stability. In particular, the candidate will be expected to
lead a growing team of edge plasma modelers aimed at understanding and
controlling the effects of impurities and neutrals on dissipation and
confinement. The candidate will have the opportunity to contribute to
international collaborative research conducted by the department with partner
fusion laboratories worldwide.
The Princeton Plasma Physics Laboratory is a world-class fusion energy
research laboratory managed by Princeton University for the U.S. Department of
Energy's Office of Science. PPPL is dedicated to developing the scientific and
technological knowledge base for fusion energy. The Laboratory advances the
fields of fusion energy and plasma physics research to develop the scientific
understanding and key innovations needed to realize fusion as an energy source
for the world.
The successful candidate will be responsible for:
Modeling key datasets from recent DIII-D experiment by simulating the edge
plasma, impurities, transport and radiation and validating those
simulations with experiment (40%)
Proposing and carrying out experiments on DIII-D to test model prediction
of the effectiveness of innovative approaches to power handling (40%)
Develop an intimate understanding of the scientific instruments that will
be the focus of modeling and model validation and participate to their
calibration and operation (5%)
Plan a program of research for junior researchers aimed at modeling and
understanding the distribution and role of neutrals on confinement and
Education and Experience:
The applicant should have a Ph.D in plasma physics and at least two years
of post-doctoral experience in fusion plasma research.
It is preferred that the applicant has broad experience in applying models
and performing data analysis for the plasma edge and scrape-off-layer.
Knowledge, Skills and Abilities:
The candidate must have excellent computer skills and demonstrated
experience in running advanced and comprehensive simulation codes.
Strong experience working with experimentalists in large research teams on
fusion facilities will be beneficial.
Preference will be given to candidates with experience in plasma
simulation with experimental application, in particular edge transport
Experience with tokamak pedestal stability and transport is highly
Familiarity with fusion plasma spectroscopy and plasma material
interaction diagnostics is a plus.
Partial shift of work time is expected to accommodate frequent
