Announcements

Monday, March 22, 2021

We’re looking forward to a successful US-PRC Virtual meeting. To ensure that everyone has the best possible webex experience, we wanted to remind you of a few things before the meeting begins on Monday, March 22 (USA time). Please note that session start times depend upon your time zone, so please plan accordingly.

1. Attached please find the final agenda
2. You can enter your meeting up to 30 minutes before the first session is scheduled to begin each day. It is important to test your system to make sure everything is in working order, such as your connection, audio, microphone, and screen sharing.
3. To join the webex meeting, please refer to the instructions that were sent you earlier this week from ahuna1 [at] llnl.gov (Lara Ahuna). Please note that the conference is webex-based, so we strongly recommend that you take a moment to familiarize yourself with the WebEx. For a two-minute tutorial video explaining how to join a Cisco WebEx Meeting, click here.
4. Because the internet may not be robust all the time, it is recommended that you pre-record your presentation video as a backup, especially for short talks. You can use your favorite software to prerecord your presentation, such as PowerPoint (Microsoft 365), and play it during the WebEx meeting. When you share your content by selecting Optimize for “Optimize for motion and video,” everyone can hear what you’re sharing through the WebEx Audio conference.
5. Upload files and videos.
6. Responsibilities of Session Chairs,
   1. Keep the session on schedule. The schedule can be found in the agenda.
   2. Play the pre-recorded video if needed.
   3. Help facilitate the Q&A. Attendee will have the ability to post questions to the WebEx Q&A and chat feature. During the presentations, please monitor these features. Once the Q&A begins, the session chair is responsible for asking the questions out loud to the speaker, as well as helping to facilitate further discussion if time permits.
   4. LOC will have team members on call as co-hosts to assist with technical difficulties, but we do ask the session chairs to be monitoring their session, answering questions and troubleshooting problems that may arise.

If you have any questions, please contact ahuna1 [at] llnl.gov (Lara Ahuna) or anderson275 [at] llnl.gov (Irene Anderson).

Thank you for your participation in the 10th US-PRC MFCW Virtual Meeting. We look forward to a successful meeting!

The tenth US-PRC Magnetic Fusion Collaboration Virtual Workshop will be held March 22-26, 2021 through WebEx. This meeting will be hosted by Lawrence Livermore National Laboratory (LLNL).

The purpose of the meeting is to harvest produce opinions, concepts and thoughts for our collaboration in magnetic fusion research between the US and China. The following topics will be discussed and with an agenda to follow soon:

• Diagnostics
• Fusion Facility Review
• Fusion Nuclear Science
• Major Collaborations
• Reactor Design & Engineering
• Theory/Simulation & Model Validation
• Technology Development

Reports of progress on existing collaborations and proposals for new collaborations are strongly encouraged. As in the previous workshops, discussions at this meeting will contribute to the planning of US-PRC magnetic fusion collaboration in the following two years, i.e., 2021-2022
