Which outcome occurs when a tokamak's toroidal field ripple significantly increases?

A)Increased runaway electron generation
B)Enhanced plasma confinement stability
C)Decreased alpha particle channeling
D)Improved impurity expulsion efficiency

💡 Explanation

An increased toroidal field ripple leads to enhanced runaway electron generation due to the **magnetic trapping** of electrons within the ripples. These trapped particles accelerate to relativistic speeds causing damage, therefore more generation, rather than plasma improvement otherwise produced by suppressing ripples using correction coils.
