1. A target for the production of nuclear particles, comprising:
a shell configured to rotate about an axis of rotation;
a reservoir containing a target material which in operation is in the liquid state, said target material being suitable for the production of said 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 from a film of the 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 fluidic connection between said gutter and said reservoir;
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, on which is generated the film of target material, a direct interaction of said accelerated particles with the film of the target material on said upper surface of the shell generating said nuclear particles; and
a fixed upper casing configured to at least partially encase said upper surface of the shell, said upper casing being traversed by said inlet pipe, wherein the gutter is secured to said upper casing and surrounds said external perimeter of the shell and curls under a lower surface of the shell, opposite to said upper surface of the shell.
