Which process limits maximum sustained fusion output from tokamaks?

💡 Explanation

Ideal plasma should be isolated within a strong magnetic field to drive controlled fusion; however, instabilities cause the field to warp, therefore plasma touches wall leading to rapid heat loss, rather than staying confined or converting fuel completely.
