Séparateur d'isotopes à double déflexion magnétique pour la production d'isotopes de très haute pureté

Laboratoire de Physique Nucléaire, Faculté des Sciences de Paris, Orsay (Seine-et-Oise)


Abstract
The electromagnetic separator of the Nuclear Physics Laboratory of Orsay is made up of a 60° sector homogeneous magnetic field analyser followed by a semi-circular inhomogeneous field analyser of the Svartholm-Siegbahn type. The enrichment factors reached are from ten to a hundred times higher than those obtained with the other types of separators while the ion beam intensity remains in the neighbourhood of 1 milliampere. A description of the instrument is given as well as the first results obtained in the séparation of the isotopes of a few éléments : Cr, Sr, Yb, Hg, U, etc...


Résumé
Le séparateur électromagnétique du Laboratoire de Physique Nucléaire d'Orsay est constitué par un analyseur magnétique à secteur de 60° en champ homogène suivi d'un analyseur semi-circulaire à champ inhomogène du type Svartholm-Siegbahn. Les coefficients d'enrichissement atteints sont de 10 à 100 fois plus élevés que ceux obtenus avec les autres types de séparateurs alors que l'intensité des courants ioniques utiles reste voisine d'un milliampère. On donne une description de l'appareil ainsi que les premiers résultats obtenus lors de la séparation des isotopes de quelques éléments : Cr, Sr, Yb, Hg, U, etc...

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
