ROF Chair / DIII-D Run Coordinator

The following agenda should be used for general planning purposes only. Since this is partly a proposal-driven workshop, the time and duration of the various sessions will likely be adjusted as required by the area leaders.

Links to information in support of the Strategic Planning Workshops are given below.  To access information identified as posted on the internal web site you will need a username/password associated with your DIII-D Cyber Access account.  If you have questions please contact Max Fenstermacher (fenstermacher@fusion.gat.com)

Plenary sessions are held in 15-019. Remote access information can be found HERE.  

NOTE:  We will use ZOOM for audio/video and ReadyTalk for slides in real time, just as we do for the Friday Science Meetings.   PLEASE MUTE YOUR AUDIO AND DISABLE YOUR LOCAL VIDEO

Details for connection to 15-019 can be found HERE

The new DIII-D 5-Year Plan for 2019-2024 can be found at the (internal) link in the NAV bar on the left of this page

TEMPLATES from Richard Buttery, to guide presenters in preparation of talks, are HERE
