DIII-D Wall Change Out Community Survey
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 forum provides a forum for all members of the fusion community to discuss considerations for the replacement of the graphite divertors and wall of the DIII-D tokamak. Please fill out the survey below to register your attendance at this meeting. Aggregate responses to multiple-choice polling questions will be distributed. Responses to long-form questions will be shared anonymously.
