Recent high-poloidal-beta (high-beta-P) experiments on DIII-D and EAST have made coordinated breakthroughs for high confinement quality at high density near the Greenwald limit. Density gradient amplification of turbulence suppression at high beta-P can explain both of these achievements. Experiments on DIII-D have achieved Greenwald fraction (fGr=... |

Zander Keith, Chirag Nagpal, Cristina Rea, R. Alex Tinguely, 2024, "Risk-Aware Framework Development for Disruption Prediction: Alcator C-Mod and DIII-D Survival Analysis", https://doi.org/10.7910/DVN/EFAWUW, Harvard Dataverse, V2
In this paper, we investigate the usage of survival analysis for disruption prediction and avoidance in tokamaks. Determining the optimal action to minimize damage from an oncoming disruption requires the plasma control system to take into account both the length of warning time and the associated risks of available actuator responses. Making time-... |

The SPARC tokamak is a high-field, Bt0 ∼12 T, medium-sized, R0 = 1.85 m, tokamak that is presently under construction in Devens, MA, led by Commonwealth Fusion Systems. It will be used to de-risk the high-field tokamak path to a fusion power plant and demonstrate the commercial viability of fusion energy. SPARC’s first campaign plan is to achieve Q... |
