DOE Workshop on Integrated Simulations for Magnetic Fusion Energy Sciences
Chair: Paul Bonoli (Massachusetts Institute of Technology)
Co-chair: Lois Curfman McInnes (Argonne National Laboratory)

Recently, Dr. Edmund Synakowski, Associate Director of Science for Fusion Energy Sciences (FES), announced a series of four technical workshops that seek community engagement and input for future program planning activities in FES, as described in a letter to the community and workshop charges, which can be found on the web: orkshops.pdf

The 2015 DOE Workshop on Integrated Simulations for Magnetic Fusion Energy Sciences, sponsored by the office of FES in partnership with the office of Advanced Scientific Computing Research (ASCR), will be held during June 2-4, 2015 in Rockville, MD. In response to the FES workshop charge, the workshop will review recent progress and identify gaps and challenges in fusion theory and computation directly relevant to the topic of disruption prevention, avoidance, and mitigation and that of plasma boundary physics, with whole device modeling as the long term goal. In addition, the workshop will reassess these challenges and their concomitant opportunities and will adjust or broaden them appropriately by taking into consideration recent progress and using the criteria of urgency, extreme-scale computing benefit, readiness for progress within a ten-year time frame, and world- leading potential. The primary workshop outcome will be a report in response to the one-page charge from FES for this workshop.

Panel Topics and Leads:
The workshop is organized into panels that broadly cover three fusion topics (A,B,C) and crosscutting issues in computational mathematics and computer science (D,E,F,G) in the context of integrated simulations for magnetic fusion energy sciences. The scope of each of these panels will build on prior workshop findings (as indicated in the resources listed below) and will include recent advances in FES SciDAC Centers and ASCR SciDAC Institutes.
