Near-term research aims to:
- Enable the success of ITER by providing physics solutions to key physics issues
- Develop the physics basis for steady-state operation in ITER and beyond
- Advance the fundamental understanding of fusion plasmas along a broad front
This group is responsible for providing physics solutions to key design and operational issues for ITER. Near-term activities of the group include suppression/control of limiting instabilitites such as neoclassical tearing modes and ELMs; development of solutions for hydrogenic retention in plasma facing surfaces; and disruption characterization and mitigation. This group is also responsible for communicating with he broader international community (e.g., the ITER Physics Team, U.S. BPO, ITPA) on key ITER issues, providing guidance from DIII-D experience, and soliciting input on ongoing ITER needs.
