Third Announcement of the 20th MHD Stability Control Workshop


This is the third announcement of the 20th MHD Stability Control Workshop ( The theme this year is “Non-linear phenomena and MHD control for ITER and beyond”. The workshop will take place on November 22-24, 2015 in Princeton Plasma Physics Laboratory, following the APS-DPP Annual meeting on November 16-20, 2015 in Savannah, GA. The workshop is organized jointly by Princeton Plasma Physics Laboratory, Los Alamos National Laboratory, Columbia University, General Atomics, the University of Wisconsin-Madison and Auburn University.


Important Note:

*  Call for Contributed Talk and Registration: Our conference has always benefited from a large number of valuable contributed talks, each of which will be 20 minutes (tentative) including Q&A. Please send your tentative contributed talk title to Marilyn J. Hondorp ( and register through the website ( as soon as possible. Early registration will help us organize the agenda and site entrance clearance permit. However, the deadline remains October 2nd.

The full workshop details and invited speakers are copied below.

  • Topics: Successful plasma control and operation of fusion reactors will benefit greatly from an improved understanding beyond the mostly established linear MHD theory. Non-linear processes such as island formation and mode dynamics are crucial frontiers in the realistic control in toroidal confinement system. In this workshop, we will discuss the leading edge theoretical and experimental works aimed at developing attractive MHD control approaches in ITER and future devices.

  • Date and Location: November 22, 9AM – November 24, 1PM, at M.B. Gottlieb Auditorium, LSB, PPPL, Princeton, New Jersey 08543-0451, USA.

  • Invited Speakers: Please find a complete list of invited speakers enclosed below or at the link on the left. Invited talks will be arranged to 35 minutes (tentative) including Q&A.

  • Call for Contributed proposals: Our conference has always benefited from large number of valuable contributed talks, each of which will be arranged to 20 minutes (tentative) including Q&A. Registration for contributed talks is open and now we call for your contribution. Please register through the website below, and also send a tentative title of your talk by email to , so we can start to prepare a draft of agenda. Late registrants may be placed on a waiting list so register as soon as possible.

  • Registration: Registration deadline is October 2, with $90 regular fee and $40 fee for students. Note the registration fee is higher than usual in this workshop due to the conference management on Sunday Nov. 22 (starting date) including lunch box. Please visit for more information and register with the payment.

  • Hotel Reservation: The most convenient hotel is the Nassau Inn located in the downtown area of Princeton and very close to Princeton University. PPPL has a limited number of rooms at a discounted rate of $127 (regular rate is $238). The deadline for hotel reservation has been extended to October 20, but please visit and make the reservation at your earliest convenience. Note the shuttle bus will be arranged for round trip between (only) the Nassau Inn and conference venue.

  • Conference dinner: We will have a banquet at the Prospect House in Princeton University on Monday night, Nov. 23. You can buy the banquet ticket ($85 for each) for you and your guest at the registration link.

  • Publication: Invited and contributed speakers will be provided with the opportunity to publish their work as fully refereed publications in a special issue of Plasma Physics & Controlled Fusion.
