Ion orbit loss and poloidal plasma rotation in tokamaks

KC Shaing - Physics of Fluids B: Plasma Physics, 1992 - pubs.aip.org
A momentum balance equation including the effect of ion orbit loss is employed to discuss

On the definition of Pfirsch–Schlüter and bootstrap currents in toroidal systems

M Coronado, H Wobig - Physics of Fluids B: Plasma Physics, 1992 - pubs.aip.org
In the plasma physics literature there appear two different definitions of Pfirsch–Schlüter
current. One of them is predominantly used in equilibrium calculations and satisfies the …
