← ScienceWhich outcome results from exceeding the Lawson criterion in deuterium-tritium fusion?
A)Ignition via self-sustaining fusion✓
B)Plasma extinguishes due ion collisions
C)Radioactive isotope creation accelerates rapidly
D)Neutron flux decreases exponentially
💡 Explanation
Exceeding the Lawson criterion means the fusion reaction generates enough heat to become self-sustaining via the mechanism of alpha heating, therefore ignition occurs rather than requiring continuous external energy because alpha particles deposit energy into plasma, increasing reaction rates.
