of the magnetic field and the mass, electrical charge, and speed of the ion. Lighter ions are more easily deflected by the magnetic field and consequently have a smaller diameter trajectory. For the separation of U235 and U238, the diameter of the 235U+ ion beam is about 0.6% smaller than that of the 238U+ ion. In an electromagnetic isotope

Chapter XI. Electomagnetic Separation Of Uranium Isotopes

CHAPTER XI. ELECTOMAGNETIC SEPARATION OF URANIUM ISOTOPES INTRODUCTION. 11.1. In Chapter IV we said that the possibility of largescale separation of the uranium isotopes by electromagnetic means was suggested in the fall of 1941 by E. O. Lawrence of the University of California and H. D. Smyth of Princeton University. In Chapter IX we described the principles of one method of

is a slow radial drift in the magnetic field which is responsible for the isotope separation.Both drifts are of the same order of magnitude. When one charged particle drifts very slowly through an environment of other charged particles it is susceptible to multiple stering.

The Pointsman Foundation MAGIS

MAGIS: THE SOLUTION M agnetically A ctivated and G uided I sotope S eparation ("MAGIS") is a new and efficient method for isotope separation that was developed by the foundation's Founder/Chairman Prof. Mark G. Raizen at The University of Texas at Austin. MAGIS was inspired by James Clerk Maxwell's vision of a fantastic pointsman, whose quick hands guide different atoms along their tracks.

Isotope separation by magnetic fields TRW Inc.

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.

Demonstration of magnetically activated and guided isotope

isotopes initially have thermal distributions of atomic states such that in a su˚ciently large magnetic field (>40G), roughly half the population of each isotope will be attracted to high magnetic field (highfield seekers) and half repelled by high magnetic field (lowfield seekers)22. In the optical pumping section, a broad 671nm laser beam,

US8672138B2 Isotope separation by magnetic activation

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.

Isotope Separation Methods ScienceDirect

A general work on isotope separation was published by London (1961) and Ravoire (1978). 201. Magnetic Field (MS Isotope Separation) The mass spectrometric measurement of isotopes is based on the separation of isotopes with different masses, and was used as an early method for isotope separation (e.g. Uisotope separation for nuclear purpose).
