Overall TSG objective: Establish predictive capability for the performance of FNSF and future devices
Thrust 1 - Characterize H-mode global energy confinement scaling in the lower collisionality regime of NSTX-U
Thrust 2 - Identify regime of validity for instabilities responsible for anomalous electron thermal, momentum, and particle/impurity transport in NSTX-U
- Low-k modes (kperp*rhos<=1): ITG/TEM/KBM, MT
- High-k mode: ETG
- Alfven eigenmodes: CAE/GAE
Thrust 3 - Establish and validate reduced transport models
