← ScienceWhich consequence occurs when a tokamak reaches the Lawson criterion?
A)Sustained fusion energy production✓
B)Plasma instability rapidly increases
C)Neutron flux decreases sharply
D)Fuel injection rate drops significantly
💡 Explanation
Meeting the Lawson criterion leads to self-sustaining fusion because sufficient reactions heat the plasma via alpha particle thermalization rather than requiring continued external heating. Energy production happens, therefore, instability does not inevitably increase; this requires other factors.
