Summary:

An electron cyclotron resonance ion source in which a plasma is confined in a magnetic configuration having a first group of coils located in the plane defined by the tight window of an ultra-high frequency injector and surrounding the latter, supplying the magnetic field creating and confining a plasma as well as a second group of coils supplied in counter-field compared with the first group and surrounding an ion extraction system. Ion extraction takes place in a magnetic field well below that corresponding to the cyclotron resonance. This ion source has numerous applications in the field of thin layer sputtering, microetching, ion implantation, accelerators, etc.

 

 

Procédé de fusion et/ou d'évapotation pulsée d'un matériau solide

Inventors:

Organization:

COMMISSARIAT ENERGIE ATOMIQUE (FR)

Publication number:

FR2512623

Publication date:

Summary:

L'invention a pour objet un procédé de fusion et/ou d'évaporation pulsée d'un matériau solide. Elle permet notamment de sublimer et de fondre des métaux, desmétalloldes, ou des matériaux composés solides… Ce procédé permet donc d'apporter sur le matériau une énergie supérieure à 1 joule sur une surface de 0,01 millimètre carré pour une seule impulsion ce qui est semblable à ce quel'on obtient avec dix impulsions laser. De plus, le rendement électrique du procédé de l'invention est voisin de celui obtenu par un faisceau continu d'électrons, c'est-à-dire voisin de50%. …

 

 

Process and apparatus for producing highly charged large ions and an application utilizing this process

Inventors:

Geller Richard; Jacquot Bernard

Organization:

COMMISSARIAT ENERGIE ATOMIQUE (FR)

Publication number:

FR2475798, également US4417178, JP56128600, GB2069230, DE3104461

Publication date:

1981-08-14

Summary:

Process for producing highly charged ions making it possible to ionize a gas of neutral atoms by electron impact, the gas being introduced into an ultra-high frequency cavity excited by at least one high frequency electromagnetic field which is associated with a magnetic field, whose amplitude is selected in such a way that the electronic cyclotron frequency associated with said magnetic field is equal to the frequency of the electromagnetic field also established in the cavity, the latter being provided with an opening for the extraction of ions by means of appropriate electrodes, wherein the said magnetic field is constituted by superimposing of a multipole radial magnetic field having a minimum amplitude in the central part of the cavity and a rotationally symmetrical axial magnetic field having a gradient along said axis, the resulting magnetic field being regulated in such a way that in the cavity there is at least one completely closed magnetic layer having no contact with the cavity walls, whereby on said layer the electronic cyclotron resonance condition is satisfied so as to obtain an ionization of the gas passing through it, the ions formed then being extracted through the extraction opening positioned in the vicinity of the outermost layer by means of extraction electrodes having no contact with said layer, followed by selection using appropriate means. Application to obtaining ions highly charged with rare gases.
