DIII-D Wall Change Community Forum

→ America/Los_Angeles
Description

DIII-D is embarking on a program to change out all the plasma-facing surfaces of the device. We are soliciting community input on the highest priority goals for this program, and what these goals imply for material selection. This open meeting provides a venue for all members of the fusion community to discuss considerations for the replacement of the graphite divertors and wall of the DIII-D tokamak.

For more information, please contact Tyler Abrams and Andrea Garofalo.
