<ul>

<li>

The PSI-Center will have three focused physics implementation groups:

the Boundary Conditions and Geometry Group; the Two-Fluid, MHD

Transport, and Relaxation Group; and the FLR and Kinetic Effects Group,

and a fourth Interfacing Group. The Center will also have a program

coordinator. We will begin with the structure as follows:

<li>

The Boundary Conditions and Geometry Group works on precise

geometry, real boundary conditions, atomic physics, neutrals, and

radiation. They work on the development of the MH4D code to

accurately model the complex geometry of many IC experiments.

</li>

<li>

The Two-Fluid, MHD Transport, and Relaxation Group works on

two-fluid/Hall, relaxation/reconnection, and MHD transport. They

develop capabilities for modeling 3D dynamics in plasmas that are

either collisional or in transition to low-collisionality behavior.

The planned tasks build upon the mature MHD algorithms and recent

Hall-MHD algorithms in the NIMROD code to produce self-consistent

two-fluid simulation models for the lower-temperature plasmas found in

EC experiments.

</li>

<li>

The FLR and Kinetic Effects Group works on kinetic and FLR effects

and focus on adding the physics needed for modeling FRCs with 3D

codes. Before it can be used to simulate FRC experiments,

time-dependant boundary conditions will have to be implemented in

NIMROD. These boundary conditions will include a vacuum field solver

to accurately represent the external coils used in theta-pinch

formation and RMF current drive experiments.

</li>

<li>

The <a href="IG.html">Interfacing Group</a> works with the EC

experiments, and the three Physics Groups. They lead the PSI-Center's

interactions with the participating experimental groups. In

coordination with the collaborating experiments, the best applicable

code and equations to be solved will be selected. The proper boundary

conditions and geometry will be implemented to start the first runs.

Methods of data exchange and communication will also be integrated

during site visits. A Summer Study for EC experimenters will be

held each summer. Graphical, user-friendly code interfaces will be

developed, and continually refined for data presentation and analysis

packages. The Interfacing Group will perform EC experiment outreach

and information dissemination through the PSI-Center web site, and

presentations at outside meetings and workshops.

</li>

<li>

In addition to assisting all the groups with administrative

tasks, the program coordinator will make an inventory of all plasma

diagnostics within OFES. The Center will assist EC experimentalists in

locating and borrowing diagnostics for making measurements needed in

calibrating and/or testing the Center's codes.
