The presence of impurities can significantly affect plasma performance since they can account for substantial radiative power losses. To keep impurity content of the plasma low, mitigating strategies (e.g., wall conditioning by titanium gettering) are employed to help pump neutrals and reduce wall recycling

Mechanisms of Ion Rotation require further investigation. Fast Ions and Field Curvature contribute significantly to the pressure balance.

To better understand and quantify the radial momentum balance in the C2 FRC plasma, experiments are performed with the mixture of Helium and Deuterium.

In the C-2 FRC plasma, low impurities densities are essential to keep the radiation losses low as well as to achieve stable high performance FRC (HPF) plasma operation.
