"density is key to net-positive fusion energy... Greenwald density limit above which tokamak plasmas become unstable exceeded by 10X, preventing machine damage even at this higher density... unlike other tokamaks, metal donut housing MST plasmas thick/ highly conducting, for more stable operation... set power providing voltage needed to maintain steady 50K amps current in plasma... most tokamaks need less voltage since: thinner walls, higher magnetic field/ temperature, produce lower-resistance plasmas"
