Isotopes are variants of a particular chemical element which differ in neutron number. For example, hydrogen (1 H), deuterium (2 H) and tritium (3 H) are three isotopes of the same element. Isotope separation is a process of separating isotopes from one another or changing their relative abundances.

Separation is a process through which a mixture is converted into two or more distinct product mixtures, at least one of which is enriched in one or more of the original mixture's constituents. [19] In the case of separating one isotope from other isotopes, this process can be modeled by a

The limitations imposed by space charges on the separation of ions in the usual magnetic mass spectrograph and the possibility of trapping electrons in the ion beam are described. It is found that high voltages and intense magnetic fields are required for moderate ion currents unless these are neutralized. Calculations are given on velocity modulated or interrupted ion beams and the ...

Mar 28, 1978· Isotope separation in a dense plasma should permit the separation of much larger quantities of the desired isotopes at much lower cost and with less expenditure of energy. Furthermore, separation of isotopes in a dense plasma is facilitated by the fact that plasma devices exist which can be used for similar processes.

A method for separation of isotopes includes vaporizing a sample having two or more isotopes of the same element. A stream of atoms is generated from the vaporized sample. One or more light waves are applied to the stream. The one or more light waves are tuned to prepare one or more specific isotopes in the flowing stream into a set of one or more magnetic states.

We propose a general method for efficient isotope separation. The principle of operation is based on an irreversible change of the mass-to-magnetic moment ratio of a particular isotope in an effusive atomic beam, followed by magnetic guiding. We show that scalability is feasible with this method ...
