Advances in Equilibrium and TSC Simulation for Plasma Control - ARIES Project Update

DESCRIPTION

The recent ARIES project meeting at Princeton Plasma Physics Laboratory presented significant updates in equilibrium and TSC simulation efforts. A new equilibrium configuration was developed to eliminate the "wave" on the inboard plasma side, simplifying the solenoid from five coils to two. Progress in TSC simulations is ongoing as we strive to maintain plasma placement against the inner wall. Objectives include optimizing plasma parameters for power plant levels, achieving high fusion power, and analyzing disruption events in line with ITER prescriptions. Further work involves enhancing impurity management and exploring structural configurations.

Presentation Transcript

  1. Update on equilibrium and TSC simulation C. Kessel Princeton Plasma Physics Laboratory ARIES Project meeting, Gaithersburg, MD, July 27-28, 2011

  2. Generated a new equilibrium to remove “wave” on inboard side of plasma Solenoid is now composed of 2 coils rather than 5 coils ✕ Will send out new eqdsk

  3. TSC simulation is progressing, not there yet Plasma lays on inner wall

  4. Work to do • Started using new equilibria in time-dependent scenario, keep plasma diverted • Raise parameters to power plant levels….obtain high fusion power • Raise density • Increase impurity/radiated power • Establish 100% non-inductive current • Establish L-H transition and ITB transition • PTRANSP for more source modeling consistency • Begin disruption sequence based on ITER disruption prescriptions • Start to examine structure configurations for disruption analysis • FW conductors, toroidally continuous vs non-continuous • Other structures/configurations that could pose conducting paths (manifolds, shield, strong-back…)
