An atomic vapor laser isotope separation in lithium was performed using tunable diode lasers.The method permits also the separation of the isotopes between the 6LiD 2 and the 7LiD 1 lines using a self- made mass separator which includes a magnetic sector and an ion beam designed for lithium.Keywords: Laser, isotopic separation.
Aug 27, 2001 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.

Jan 29, 2014 The propagation of a metal plasma jet in a transport system with a curvilinear magnetic field was studied experimentally.The jet was generated by a pulsed vacuum arc discharge with a composite (W + Fe) cathode.Spatial separation of ions of the cathode material was observed at the exit from the system.
Lanthanides play an important role in modern technology because of their outstanding optical, electronic, and magnetic properties.Their current hydrometallurgical processing involves lixiviation, leading to concentrates of elements whose separation requires exhaustive procedures because of their similar chemical properties.In this sense, a new nanotechnological approach is here discussed .
Magnetic Sector Mass Analysis 20.3 : 3/12 Ion momentum is determined by its mass and velocity.The velocity is determined by the amount of kinetic energy obtained in the source, mv2/2 = qV s.To obtain the behavior of the magnetic sector with respect to m/z, square the momentum equation and substitute in the kinetic energy.
Oct 14, 2019 Nearly all rare‐earth separations rely upon small changes in ionic radii to direct speciation or reactivity.Herein, we show that the intrinsic magnetic properties of the rare‐earth ions impact the separations of light/heavy and selected heavy/heavy binary mixtures.
One of them was the construction of a separated sector cyclotron (SSC) t,o use the beams produced by the K1200 cyclotron and boost the energy of fully stripped light ions to 500 MeV/u with high intensities.
The Pierce extractor yields a divergent ion beam that is focused with an Einzel lens system into the entrance of a mass selector.This mass selector was made in-house and is comprised of an ion gun and a magnetic sector.To calibrate the mass selector we have used a lith-Fig.
Sep 01, 1995 1) In a magnetic separator in which ions move in a vacuum of = 10-7 mbar for a few meters, several percent of the ions are scattered at residual gas atoms.Some of the ions of the undesired mass mt thus are scattered such that they pass through a separator exit slit that was properly positioned for the transmission of ions of mass mo only.
Since then the separator has served mainly as a proto- * Work supported by the U.Atomic Energy Commission under Contract AT(11-1)-535.Type instrument and has been used for studies aimed toward improving the characteristics of the velocity filter.Results show that this type of separator has more flexibility than the magnetic sector machine.
Stable beams of light (p, 3 He, 4) and heavy (36,40 Ar, 58 Ni, .) ions are provided by the CYCLONE-110 isosynchronous cyclotron to induce fusion-evaporation reactions as well as fission reactions of thin targets.The targets are placed in a buffer gas of He or Ar at 500 mbar to catch and thermalise the produced radioactive isotopes.
The invention relates to a mass spectrometer having a magnetic sector analyzer in which the magnetic field is developed neither by a permanent magnet nor by an electromagnet having the conventional ferromagnetic core.In particular, the spectrometer has a magnetic sector analyzer through which ions of a mass-to-charge ratio selected by said analyzer may travel along a substantially circular .
