← ScienceWhich outcome occurs when energy input falls during inertial confinement fusion?
A)Plasma cools; fusion yield drops✓
B)Fuel undergoes spontaneous neutron emission
C)System shifts to nuclear fission
D)Deuterium spontaneously turns to Helium
💡 Explanation
If external sources can't maintain the DT plasma, thermal energy quickly drops because radiative losses exceed fusion power generated, causing the **bremsstrahlung effect**. Plasma temperature drops rapidly, therefore fusion ceases rather than increasing neutron emissions under these conditions.
