Calculations of Ion Trajectories at Magnetoplasma Separation and Experiments With Polyatomic Gases

Abstract

Abstract. Calculated trajectories of ions with different masses, indicating the possibility of a mixture separation, are obtained. Comparative experiments for plasma of monatomic and polyatomic gases (Ar, N 2 , CO 2 ), upon combination of pulsed discharge with a stationary one with incandescent cathode, are carried out. The oscillograms of discharge current and voltage at low emission currents and a constant energy input show that energy is spent on other processes different from ionization. With an increase of emission current, the nonlinear character of the discharge current and voltage, which may be indicative of the role of dissociation and vibrational levels in energy consumption, is observed. In addition, there is connection between the number of atoms in molecule and the values of maximum discharge current and the pressure of injected gas.

The Atomic-Molecular Processes in a Hydrogen Plasma at Initial Stage of a Discharge

“…where m  is the number of collisions of a hydrogen atom with a wall before recombination. (8) where P h , P ion , P r , P rad going to plasma heating, ionization, recharging, emission of impurities; V pplasma volume; k -is the Boltzmann constant. ,…”

“…That is, hydrogen plasma with impurities is a kind of simulation environment, allowing you to look at the spent nuclear fuel plasma from the view of atomic-molecular processes in SNF plasma formed mainly from actinide oxides supplemented with a mixture of oxides of lanthanides, zirconium, molybdenum, etc. [8].…”

Finite-Difference Multiple Fluid Solution for Source-Driven Rotation in Highly Magnetized Linear Plasma Device

“…Cylindrical plasma geometry is used in fusion applications such as mirrors 1,2 , z-pinches, MagLIF [3][4][5][6] , and in some centrifugal fusion concepts [7][8][9][10][11] . They are also used for mass separation [12][13][14][15][16][17][18][19][20] . Investigation of classical transport effects is a first step in modeling of these devices.…”

Generalized Impurity Pinch in Partially Magnetized Multi-Ion Plasma

“…Some progress was also made in a study of multi-ion-species transport in a magnetized plasma in the presence of temperature gradients was made by Vekshtein et al 22 , although the authors did not have external forces and they had a specific configuration in mind, which is different from this paper. The expansion of the range of applicability of muti-ion collisional transport models is also useful for plasma mass filters, which are designed to separate the components of a plasma according to mass [23][24][25][26][27][28][29][30][31][32][33] for a variety of applications [34][35][36][37] .…”
