Headed to Madison!

• List of Initiatives that will be reviewed has been posted.
• Advocacy groups have been contacted with initial Evaluation details and initial draft of Gaps/Metrics for this Expert Group

Mission

What are the expected outputs of this Expert Group?

• Provide feedback to Advocacy Groups by evaluating the scientific and technical accuracy of their ideas and initiatives.
• Evaluate the breadth of Advocacy Group input relative to the previously identified needs (ReNeW, 2015 PMI Workshop Report, etc) and identify and solicit the community to suggest ideas to close these remaining gaps.

What will the Expert Group NOT do?

• Provide public-facing output on recommendations and prioritization of the various Advocacy Group initiatives.

Note for this Expert Group, there is a some overlap with a the PMI/PFC Expert Group in Fusion Materials and Technology Topical Area. We will coordinate with that Expert Group to make sure ideas aren't lost, but expect that both will provide some overlapping feedback on Initiatives.

Getting Involved

This Expert Group is open to anyone who is looking to participate, and should contact the Leader listed above. You can get involved a little or a lot, but we will ask for certain minimum amount of time that can be devoted to this process to ensure we have the resources we need. The internal deliberations and discussions of the Expert Group are kept private to ensure an open and free exchange of ideas, while the output will be accessible (see below)

If you simply want to provide suggestions or anonymous input, then you can use the submission form.

Our Expert Group presently meets on (TBD) via Zoom as well as circulates discussions via (TBD)

Initiatives the Expert Group is Currently Evaluating

Types of initiatives that will be evaluated by this expert group:

• Facilities and experimental programs for demonstration of divertor physics (e.g. effects of geometry, topology and materials)
• Facilities and experimental programs for demonstration of integrated exhaust scenarios (e.g. core/edge integration, power exhaust, particle control)
• Development and testing of required auxiliary systems and actuators for influencing boundary plasma (e.g. fueling, seeding, wall conditioning)
• Development and validation of reduced physics models/codes (for above)
• Development and validation of full physics models/codes (for above)
• Diagnostic measurement and analysis needs, integration and R&D (for above)

Topical Areas

To facilitate the evaluation of initiatives from Advocacy Groups, we have organized the Expert Group in the follow sub-topical areas.

• at this point we have not needed to further break up the Expert Group

Provide Input to the Expert Group

There are multiple ways that you can provide input and we would like to get as much feedback from the community as possible. You can

• Provide input through the submission form which can be linked to your name or provided anomalously*
• Directly e-mail the Expert Group leader and/or members who can share your concerns during our internal discussions
• Join the Expert Group and get involved directly - we understand you are busy and so can try to accommodate your participation

*The purpose of allowing anonymous input is to make sure people can provide evaluation and criticism of ideas that may be linked to their on-going research area and are worried that feedback negatively impact their career progression. If providing feedback anomalously, you will need to lay out a reasoned argument, including citations to prove your point as we won't be able to rely on name/title/position/experience to provide context.
