Overall TSG objective: Develop the basis for integrated, steady-state operation and axisymmetric control for next-step STs, while helping resolve key scenario and control issues for ITER

Thrust 1 - Scenario Physics
• Development of 100% non-inductive operation
• Extend the high-current, partial-inductive scenarios to long-pulse

Thrust 2 - Axisymmetric Control Development
• Develop methods to control the heat flux for high-power scenarios
• Develop rotation and current profile control

Thrust 3 - Disruption Avoidance By Controlled Discharge Shutdown
• Develop detection of impending disruptions
• Develop techniques for the automated termination of discharges

Thrust 4 - Scenario Physics for Next Step Devices
• Determine the optimal, simultaneous q- and rotation profiles
• Study the conditions for classical beam current drive
• Explore & validate integrated models for projections to FNSF
