All information about this meeting, including instructions on how to access it remotely, is available at http://science.energy.gov/fes/fesac/meetings.
USBPO Web Seminar
Topic: Recommendations for ITER Experimental Operations Procedures and US ITER formation and management
Speaker: Rajesh Maingi, PPPL
Date: Wednesday, September 24, 1:00 pm EDT (noon CDT, 10am PDT)
Dr. Maingi has been leading a USBPO task group which has been considering issues regarding the experimental phase of ITER, and how US scientists would like to participate for maximum effectiveness. This includes how the US team should be formed, and for ITER experimental operations, for example regarding experimental proposals and access to experimental data by the team. While this phase may seem far off, the IO is making technical decisions now which will affect future capabilies; this is an opportunity for input from the US community. The work of this task group is nearing completion. The seminar will present its draft recommendations, and input from the USBPO membership is welcomed during the discussion, and in writing afterwards.
Connection details will be sent by email.
Registration Deadline for the ITPA Transport and Confinement Topical Group Meeting
The next ITPA Transport and Confinement Topical Group Meeting will take place in Cadarache, France at the ITER IO on October 20–22, 2014.

As you know, the annual US Burning Plasma Council election concluded recently. Thanks to your nominations and an excellent job by our nomination committee (Larry Baylor, Jerry Hughes, Chris Hegna, David Mikkelsen, and Gary Staebler [chair]), we had a slate of very strong candidates to choose from. It is now my pleasure to announce that the winners of the election were Jim Terry (MIT) and David Brower (UCLA).
In accordance with the Bylaws of the USBPO, two additional members were appointed to fill out the full Council membership of 12. The new appointed Council members are Juergen Rapp (ORNL) and François Waelbroeck (University of Texas).
I want to thank the outgoing members of the Council (Chris Hegna, Jerry Hughes, Tom Rognlien, and Don Spong) for their valuable service to the community, and hope they will continue to be active as we work to increase the effectiveness of the USBPO.

You may remember that two years ago, when Jon Menard was named as Chair of the Council and Mark Koepke as Vice Chair, we indicated that Jon’s term would be for two years. Due to Mark’s other commitments, we are waiting until after the APS–DPP Conference, after which time Mark will become Council Chair and we will name a new Vice Chair.
At this time, the leaders of five of our Topical Groups are nearing the end of their terms. Each of the associated deputy leaders has agreed to step up to lead their groups. We are in the process now of selecting new leaders for each of these groups. You should hear more about this in the coming weeks.

ITER achieves a major milestone
ITER reached a major milestone this past Wednesday with the completion of the B2 slab. The process of pouring the foundation for many of the most central parts of the ITER facility, including the tokamak itself, took eight months, 14,000 cubic meters of concrete, and 3600 tons of rebar. With the achievement of this milestone, work is expected to accelerate as the tokamak complex begins to rise on top of the slab in the coming months.

|The 12th Meeting of the ITPA Transport and Confinement Topical Group took place at the Massachusetts Institute of Technology on April 9–11, 2014, hosted by John Rice and the MIT-PSFC. Approximately 48 scientists registered and participated on site or remotely: approximately 22 from the US, many from Europe, and a few from Japan. Several MIT-based scientists and professors who don’t normally attend ITPA-TC meetings participated and provided valuable talks and contributions. Alberto Loarte represented ITER. The meeting consisted of 9 sessions. Topic and highlights presented:|

|6) 3D effects: Collisionality effects, impact on L-H transition threshold, simulations, W7-X perspective, updates from D3D, TJ-II and a W7-X perspective|
|7) L-mode shortfall: impact of rotation/ExB shear, C-MOD and AUG results from GYRO & GENE, modeling of the strong q-dependence|
|8) Fueling/Particle transport: MAST results, simulations, effects of flat or hollow density profiles in ITER, pellet, gas puffing effectiveness, tungsten radiation limits, poloidal asymmetries of W, impurity transport|
|9) Thermal transport: WEST (Tore-Supra upgrade) for ITER risk mitigation, expected tungsten content, TGLF predictions for ITER, micro tearing mode effects on Te-profile, flux-driven simulations of barrier dynamics w/ExB|
