← ScienceWhich outcome results when a tokamak's plasma current collapses?
A)Increased neutron flux emission occurs✓
B)Cryostat temperatures rapidly decrease
C)Toroidal field magnets demagnetize slowly
D)Plasma density instantly reaches zero
💡 Explanation
Increased neutron flux emission occurs because the magnetic confinement fails; this prompts more fusion events during the thermal quench via Bremsstrahlung radiation. This outcome is preferred, therefore increased neutrons rather than cryostat temperature decrease, because no additional coolant enters the cryostat.
