← ScienceWhich instability grows when fusion fuel density drops?
A)Rayleigh-Taylor instability dominates plasma behaviour✓
B)Parametric decay heats target unevenly
C)Beta limit restricts plasma confinement
D)Kinetic instability cools the fusion target
💡 Explanation
Lower density increases the Rayleigh-Taylor instability during inertial confinement fusion, because the pressure gradient opposes acceleration, therefore turbulent mixing increases and fusion decreases, rather than parametric decay or beta limit instability taking over.
