HALO CURRENT Meaning and
Definition
-
Halo current refers to electric currents that flow in the surrounding plasma of a plasma device, such as a tokamak, which is a type of nuclear fusion reactor. The term "halo" is used because these currents form a ring-shaped configuration around the central plasma column.
In a tokamak, there are powerful magnetic fields that confine and control the plasma. However, due to certain instabilities or disruptions in the plasma, some plasma particles can be lost from the main plasma column and enter the space between the plasma and the surrounding walls. These particles then create a localized region of lower density plasma known as the halo region.
As a result, halo currents are induced in this region due to the interaction between the plasma particles and the magnetic field. These currents flow in closed loops, parallel to the plasma-wall interface. The halo currents can cause several effects and issues, such as excessive heating of the plasma-facing components, impurity production, and perturbations to the plasma stability.
Understanding and controlling halo currents are important for the safe and efficient operation of plasma devices. Research efforts focus on developing strategies to mitigate halo current effects, such as using magnetic field configurations that minimize the loss of particles and implementing materials with higher thermal tolerances. Proper management of halo currents is crucial in the pursuit of sustainable and long-lasting fusion reactions, which hold significant potential as a clean and abundant source of energy.
