Generalized impurity pinch in partially magnetized multi-ion plasma

In a two-ion-species plasma with disparate ion masses, heavy ions tend to concentrate in the low-temperature region of collisionally magnetized and high-temperature unmagnetized plasma, respectively. Moreover, collisional magnetization can be determined as ratio light gyrofrequency collision frequency species, behavior this effect intermediate regime partially is predominantly dependent on Hall parameter. Multi-ion cross-field transport has been described before regime, generalized pinch relations, which describe densities species equilibrium that are found literature. paper, role Larmor multi-ion clarified, relations extended parameter may small, long electrons remain magnetized. Equilibrium density profiles have same dependence external forces each other regardless ions. The expansion range validity models makes them applicable wider laboratory conditions. particular, evolve sufficiently fast for radial impurity observable around stagnation MagLIF, leading expulsion impurities from hotspot becomes during implosion.
