← ScienceWhich outcome occurs when a tokamak is cooled below its critical quench temperature?
A)Plasma confinement is abruptly lost✓
B)Fusion power output increases linearly
C)Helium-3 flash boiling is eliminated
D)Neutron flux attenuates asymptotically
💡 Explanation
When the superconducting magnets quench, the **Meissner effect** is eliminated. Confinement is lost because magnetic fields collapse, therefore plasma hits the walls, rather than reaching stable fusion conditions or gradually attenuating.
