FY2008 NSTX Research Forum
27 - 29 November 2007
The
National Spherical Torus Experiment (NSTX) Research Forum
for 2008 is scheduled for November 27 - 29, 2007 at the
Princeton Plasma Physics Laboratory in Princeton, NJ USA.
Team members and prospective collaborators are invited to
attend or participate remotely.
The
Research Forum is intended to provide team members the
opportunity to present ideas for experiments to be
conducted on NSTX in the forthcoming run. Both
well-developed and new ideas in the early stages of
development are welcomed. For the 2008 experiments
Proposals for experiments to be performed in 2008 can be
submitted for discussion at the Research Forum through
this website.
There
are no registration fees for the meeting, but
researchers from other institutions must pre-register to
participate. Intending participants from other
institutions who are US citizens should send their names
and affiliations to Joanne Savino (JSavino@pppl.gov)
to register; non-US citizens will need to submit a
PPPL Foreign Visitor
form in advance of the meeting. Please email Joanne
Savino (JSavino@pppl.gov)
as soon as possible.
High Priority Experimental Goals for 2008 (see each area for all priorities; all ideas are welcome)
- Characterize divertor heat flux and access to detachment (R08-3); compare divertor heat flux widths to midplane density and temperature widths and edge turbulence characteristics
- Determine relationship of ELM properties to discharge boundary shapes and Lithium conditioning, and compare stability of pedestal/ELMs with model calculations
- Assess active and passive RWM stabilization physics for improved mode control (R09-1)
- Evaluate MHD sources of plasma viscosity and assess the impact of plasma rotation on plasma stability, including NTM (Joule milestone)
- Assess the role of flow shear in controlling plasma turbulence and transport using poloidal CHERS (R08-1)
- Evaluate the generation of plasma rotation and momentum transport, and assess the impact of plasma rotation on stability and confinement (Joule milestone)
- HHFW/EBW - Understand and improve coupling to and heating of H-mode deuterium NBI-heated plasmas
- Fast Ion MHD - Assess fast ion transport from TAE avalanches and compare to non-linear TAE simulation
Solenoid-Free Startup and Rampup
- Demonstrate ohmic flux savings using CHI
- Couple inductive ramp-up to CHI plasmas (R08-2)
Advanced Scenarios and Control
- Characterize non-inductive current drive fraction versus density, shaping and q
- Attempt to achieve long-pulse density control using improved fueling and Lithium conditioning
