Thus, the two processes, magnetic field penetration and ion separation, are closely linked, and occur simultaneously. Since very often plasmas in opening switches and in other pulsed devices are multi-ions with ion-composition nonuniformity, our analysis shows that magnetic field penetration is a much more general process that has been ...

2001-8-27 The magnetic field, the electron density, and the ion velocities in a multispecies plasma conducting a high fast-rising current are determined using simultaneous spectroscopic measurements. It is found that ion separation occurs in which a light-ion plasma is pushed ahead while a heavy-ion plasma lags behind the magnetic piston. We show that most of the momentum imparted by the magnetic field

2000-7-1 It is shown that a curved magnetic field can be used to separate ions in a multicomponent plasma. Without selective ion preheating, the separation over one cycle is inefficient: the separated ion fractions will only be enriched with ions of the corresponding isotopes. Selective ion cyclotron resonance heating makes it possible to achieve essentially a complete separation of the ions.

2003-12-2 The magnetic separation was investigated for Co 2+ (9500 × 10-6 cm 3 mol-1) and Fe 3+ (14600 × 10-6 cm 3 mol-1) ions and for Cr 3+ (6200 × 10-6 cm 3 mol-1) and Al 3+ (−2 × 10-6 cm 3 mol-1) ions. The metal ion solutions were spotted on a silica gel support, and exposed to a magnetic field of 410 kOe 2 cm-1 intensity × gradient.

Magnetic sector instruments, in which ion separation is achieved by passage through a magnetic field, allow high-resolution spectra to be acquired for the calculation of elemental compositions. Although maximum scan speeds are lower than with quadrupole-based systems, as a result of magnetic hysteresis, they are sufficient for most applications.

2003-12-2 The magnetic separation was investigated for Co2+ (9500 × 10-6 cm3 mol-1) and Fe3+ (14600 × 10-6 cm3 mol-1) ions and for Cr3+ (6200 × 10-6 cm3 mol-1) and Al3+ (−2 × 10-6 cm3 mol-1) ions. The metal ion solutions were spotted on a silica gel support, and exposed to a magnetic field of 410 kOe2 cm-1 intensity × gradient. The Co2+ ions move farther toward the maximum field than the Fe3 ...
