← ScienceWhich outcome in a tokamak fusion reactor increases when plasma density exceeds the Greenwald limit?
A)Radiative power loss becomes dominant✓
B)Ion cyclotron resonance decreases sharply
C)Alpha particle confinement dramatically improves
D)Bootstrap current generation efficiency peaks
💡 Explanation
When plasma density hits the Greenwald limit, increased collision frequency triggers enhanced Bremsstrahlung radiation, and radiative power loss becomes dominant because the radiation heat flux overcomes confinement, therefore cooling the plasma, rather than sustaining fusion conditions.
