Axial ion source emitting a high intensity beam for a cyclotron
Description
The present invention relates to an axial ion source of Penning type intended for providing a high intensity ion beam towards the center of a cyclotron. It comprises a tubular anode provided at one end with a cathode made of a filament heated at high temperature and, at the other end with an anticathode. Said anticathode consists in a circular plate fitted with a connecting mandrel whose axis YY is parallel to that of the anode and perpendicular to said plate. Said mandrel can slide inside a guiding sheath located at the center of the support for fixing the anticathode onto the polar part of the cyclotron, so as to make YY axis to coincide with that of the cyclotron and rigidly connect the anode and cathode to the other polar part. Said mandrel is joined to a member controlling the sequential rotation of the cathode around YY axis and means of longitudinal displacement of the anticathode along side YY axis

La presente invention a pour objet une source d'ions axiale permettant de fournir un faisceau d'ions de haute intensite au centre d'un cyclotron. Cette source est du type 'source de Penning'. Elle comporte une anode tubulaire aux extremites de laquelle sont disposees respectivement une cathode constituee d'un filament pouvant etre porte a haute temperature et une anticathode. Ladite anticathode est constituee d'un plateau circulaire muni d'un mandrin d'axe YY parallele a celui de l'anode, et perpendiculaire audit plateau. Le mandrin peut glisser dans un fourreau de guidage dispose au centre d'un support permettant de fixer l'anticathode sur l'une des pieces polaires du cyclotron, de facon que l'axe YY coincide avec celui du cyclotron, et de rendre l'anode et la cathode solidaires de l'autre piece polaire. Ledit mandrin est associe a un dispositif permettant de commander la rotation sequentielle de l'anticathode autour de l'axe YY et des moyens permettent le deplacement longitudinal de l'anticathode suivant l'axe YYAdditional details
