Study of axial injection of polarized protons into the grenoble cyclotron; Contribution a l'etude de l'injection axiale pour protons polarises sur le cyclotron de Grenoble

Abstract

By injecting ions axially into a cyclotron, it is possible to accelerate particles (polarized particles, heavy ions, etc...) obtainable only with difficulty when an internal ion source is used. In this work, after justifying the choice of an axial injection device equipped with a 'pseudo-cylindrical' deflector for the Grenoble cyclotron, we study theoretically the principle of such a detector, the choice of its parameters, and the effect of this choice on the conditions of acceleration of the beam by the cyclotron. From the experimental point of view, this report describes two operations which made it possible to check that the chosen injection device operated satisfactorily, qualitatively initially (electron model), then quantitatively (proton model). In conclusion, we believe that the Grenoble cyclotron thus equipped will be able to provide a relatively dense beam of polarized protons.

Du point de vue experimental, ce rapport decrit deux manipulations qui ont permis de verifier le bon fonctionnement du dispositif d'injection retenu, qualitativement d'abord (modele a electrons), quantitativement ensuite (maquette a protons). En conclusion, nous estimons que le cyclotron de Grenoble ainsi equipe, peut fournir un faisceau relativement intense de protons polarises. (auteur)}
