The project structure has been refined in line with the TWG “W7-X Strategy 2030” final report, separating divertor development into:
• 1a – Definition of divertor geometry
• 1b – Technology development and qualification
The leadership reflects the inter-divisional nature of this project:
• Joris Fellinger (E5) – Project Lead & Lead Engineer (W7-X machine constraints & technology)
• Thierry Kremeyer (E3) – Responsible Officer & Project Manager (Geometry design cycle, documentation, project coordination)
• Robert Davies (ST) – Lead Physicist (Theory, consultation, knowledge base)
Agenda:
1. Introduction to the project mission and scope
2. Presentation of project plan and milestones
3. Project team, roles, and responsibilities
4. Communication channels and meeting structure
After the meeting, I would be delighted to host a small BBQ to continue our discussions in a more informal setting. Please RSVP so I can plan food and drinks accordingly, and let me know if you would like to contribute something.
There are multiple divertor undertakings happening at IPP.
Solution of overload middle divertor part 5H/6H (Grulke):The W7-X Physics Board unanimously approved the formation of a Temporary Working Group to discuss potential solutions to mitigate or harden the middle divertor section. The TWG will address the following questions: Is an exchange feasible, what would be the technical basis for this, what would be the consequences if it were implemented. The TWG’s results will be available by the end of the year. Chair Grulke, futher members Fellinger, Gao, Lorenz, Reimold. |
Investigation of long-term divertor and PFC material options (Wolf): |
The Physics Board approved the formation of an adhoc group to define the mission of a TWG (by October 2025). Chair (Wolf), further members Naujoks and Reimold. The idea is to outline a mission with possible constraints.
Boundary conditions need to be defined. Balance between W7-X and reactor relevance.
The configuration space is rather large. While manageable for the low fidelity cycle, a prioritized sequence should be defined for the high fidelity cycle.
