Leaders
of the various task force areas organized meetings following the Ideas Forum to
evaluate and prioritize the proposed ideas. Results of these meetings have
informed the overall planning of the FY2007 run campaign. Summary documents
from these meetings are included in the table below.
Note: No proposals were submitted this year in the Basic Science topic.
Several task forces have been formed to help guide the planning of the
C-Mod experimental program. Interested parties are encouraged to contact the
appropriate coordinators prior to submitting their ideas.

Description
|
|
Integrated
Scenarios
|
Research aimed at
reaching attractive operating points, generally cutting across multiple science
topics and often involving interaction and compatibility issues between
different plasma processes or regions. Naturally, there is considerable
topical overlap between the IS areas and the various science areas.
|
|
IS: H-mode Baseline
|
Steve
Wolfe
|
Issues related to
conventional H-mode as baseline operational scenario for ITER: projection
of H-mode threshold, pedestal scalings and ELM behavior; confinement optimization;
startup and heating schemes; H-mode fueling and density control; density
limits; wall materials choices; divertor and first wall heat loads;
disruption mitigation.
|
|
IS: Advanced Scenarios
|
Amanda
Hubbard
|
Additional issues related
to hybrid and steady-state scenarios: access to hybrid scenario with
coupled electrons/ions using lower hybrid current drive; formation and
control of internal transport barriers; control of transport barriers
through current profile control; RF Flow drive; current profile
modification techniques other than LHCD; j(r) measurements; long
pulse power handling.

Topical
Science Areas
|
|
|
Lower Hybrid
|
Randy
Wilson (PPPL)
|
Covers issues associated
with: improvements to LH launcher operation; preparing suitable H-mode target
plasmas for LHCD; launching and absorption of LH waves; direct LH effects
including heating and current drive; interactions between LH and ICRF.
|
|
ICRF
|
Yijun
Lin
|
ICRF issues include: wave
propagation and absorption; mode conversion; directed waves and current
drive; general wave-particle interactions and those that provoke a unique
plasma response (e.g. ITB's); antenna behavior and RF interactions with
material surfaces.
|
|
Transport
|
Martin
Greenwald
|
The transport program
includes: studies of edge fluctuations and stability including EDA and ELMy
H-modes and the role of turbulent transport in the density limit; the L/H
threshold and transition dynamics; the role of critical gradients and
marginal stability in core transport; ITB thresholds, dynamics, sustainment
and control; the origin and role of rotation in systems without direct
momentum sources; and particle and impurity transport.
|
|
Divertor/Edge
|
Dennis
Whyte
|
The divertor/edge program
includes: studies of main chamber and divertor recycling; SOL transport,
turbulence and scalings; divertor power handling, plasma/surface
interactions and impurity generation; the physics of detachment, volume
recombination processes, opacity, and modeling of the divertor and edge.
|
|
MHD
|
Bob
Granetz
|
The MHD task force covers
MHD instabilities and disruptions.
|
|
Basic Science
|
Bill
Rowan (UT-Austin)
|
The Basic Science area
includes atomic physics and astrophysics-relevant studies that utilize the
plasma as a well diagnosed, hot light source.
|
|
Diagnostic Development
|
Steve
Scott (PPPL)
|
The diagnostic
development area includes proposals for novel plasma diagnostics for
implementation on C-Mod; improvements to existing diagnostic capability;
and ideas for improved analysis techniques.
|
|
Operations
|
Jim
Irby
|
Covers experiments that
impact machine operation: including cryopump operational development and
optimization; specialized uses of the digital plasma control system;
startup optimization; and evaluation of new wall-conditioning techniques.
