13th US TRANSPORT TASK FORCE WORKSHOP
BURLINGTON, VERMONT
APRIL 26 - 29, 2000
Discussion Sessions
In addition to meetings of the working groups, we are going to schedule a number of focused discussion sessions during the TTF workshop. These would run for 1-3 hours depending on the level of interest and would stress open discussion rather than prepared presentations. In each case the organizer would schedule a few short talks to help frame the issues and call on additional speakers with 1 or 2 vugraphs only. The goal would be to generate dialogue and suggestions for further work on topics of interest. While everyone is free to participate in these sessions, those who wish to contribute more actively should contact the organizers listed below.

Further focussed topical discussion will take place in the context of the working group sessions.  For reference, these are listed as well.
Proposed Topics for Discussion
Methods for Comparing Experimental Data to Theory and Modeling

Quantitative comparisons of steady state temperature profiles are a necessary but not sufficient criterion for evaluating theories of plasma transport.  Following up on the Core Transport working group meeting in Seattle, we would like to encourage short presentations and discussion concerning other modes of comparison.  Unique and essential properties of theories need to be matched with viable experimental techniques. Advanced time series analysis of fluctuations, which was discussed in the Seattle session, would be included along with methods for 2D or 3D turbulence visualization,  the study of transient transport phenomena, measurement of additional turbulent fields, etc.

Complex Dynamics of Transport in Magnetically Confined Plasmas

Considerable progress has been made in understanding anomalous transport in magnetic confinement devices;  nonetheless, our understanding of the complex dynamics underlying the anomalous transport process is incomplete. Outstanding issues include transport in sub-critical and marginal systems, universality of turbulence and transport, diffusive versus non-diffusive transport, and self-organization. We particularly encourage contributions on inter-machine or machine-model comparisons.

Additional Topics for Focus in Working Group Sessions
Theory/Computation Comparisons

This year, presentations on developing the theoretical understanding of simulation results will be given priority for oral presentations in the Modeling Group.  Requests for oral presentations on experimental comparisons will be forwarded for consideration in the "Methods for Comparing Experimental Data to Theory and Modeling" session.  Presentations discussing code and algorithm development will be assigned to poster sessions by default.  Of course, outstanding presentations on any aspect of modelling will be considered for Invited Talks.

Organizer: Bill Dorland (bdorland@kendall.umd.edu)

Physics of H-Mode

The H-mode Working Group solicits contributions from the experimental,  theoretical and modelling communities on H-mode issues.  Topics of current interest include developing and testing models of the L-H transition,characterizing the height and width of the H-mode transport barriers and discerning the physics which controls the height of these barriers.  Several subjects related to core-SOL coupling are important for these studies.These subjects include edge fluctuations and transport, neutrals and 2D effects related to the existence of an X-point.  Appropriate contributions from these subjects are also solicited.

Organizer: Rich Groebner (groebner@fusion.gat.com)

Brainstorming on methods to attack the problem of particle and electron transport

While considerable progress has been made on the problem of ion energy transport, significantly less attention has been paid to the electron energy and particle channels.  We are planning a short "brainstorming" session where participants can discuss new ideas and approaches.
