← ScienceWhich consequence increases when a Tokamak reaches high beta?
A)Increased disruptive plasma instabilities✓
B)Increased neutron flux shielding needs
C)Reduced charged particle confinement
D)Suppressed alpha particle heating
💡 Explanation
Plasma instabilities rise, because increases in beta, a measure of plasma pressure relative to magnetic field pressure, lead to greater Magnetohydrodynamic (MHD) instabilities; therefore plasma disruption increases, rather than better confinement or reduced neutron flux, which would require different controlling mechanisms.
