Liquid targets for the production of nuclear particles

Abstract

According to one aspect, the present description concerns a target () for the production of nuclear particles. The target comprises a shell () formed by a surface of revolution and mounted in rotation about an axis of rotation () that coincides with an axis of revolution of the shell. The target further comprises a reservoir comprising a target material in the liquid state during use, the target material being suitable for producing the nuclear particles; a target material raising device configured to entrain, in operation, the target material from the reservoir toward an upper surface () of the shell; a gutter formed along an external perimeter () of the shell and configured to receive, in operation, droplets derived from a film () of target material induced by centrifugal action on said upper surface of the shell as the shell is rotated; at least one return pipe forming a fluid connection between the gutter and the container; an inlet pipe configured, in operation, to let in a beam of accelerated particles into a zone of impingement of said accelerated particles with the shell, said zone of impingement being situated on said upper surface of the shell, the interaction of said accelerated particles with the target material circulating on said upper surface of the shell generating said nuclear particles.
