The embodiments of the present disclosure provide a method for producing Ac-225 from Ra-226, comprising submitting Ra-226 to a photo-nuclear process, collecting an electrochemical precipitation of an Ac-225 on a cathode in a recipient, removing the cathode from the recipient after the electrochemical precipitation of the Ac-225, transferring the cathode to a hot cell environment, and extracting the Ac-225 from the cathode in the hot cell environment. The Ra-226 may comprise a liquid solution in the recipient, and submitting Ra-226 to the photo-nuclear process may comprise irradiating the Ra-226 to produce Ra-225. The Ra-225 may decay into Ac-225 upon irradiation of the Ra-226.

Method for producing Ac-225 from Ra-226

A capsule for the transfer of a target material in a conveying system between a target irradiation station and a collecting station comprising: a beamline channel for the passage of an energetic beam irradiating the target material, a target holder holding the target material or a substrate backing the target material at a glancing angle with respect to the beamline channel axis, a degrader foil positioned across the beamline channel for degrading an energy of the energetic beam upstream of the target material, a target cooling inlet and a target cooling outlet for passage of a cooling fluid in a target cooling duct in a vicinity of the target holder such that the target material can be cooled during an irradiation, and a degrader foil cooling inlet and a degrader foil cooling outlet for passage of a cooling gas in a vicinity of the degrader foil.

System for the irradiation of a target material

A cyclotron for accelerating a beam of charged particles and extracting the beam. The cyclotron includes a vacuum chamber; a target support element sealed and coupled to the vacuum chamber and including a tubular channel leading to a target; first energy specific extraction kit including a first stripper assembly with a stripper located at a first stripping position for stripping charged particles at a first energy and a second energy specific extraction kit for driving modified charged particles of second energy along a second extraction path towards a target holder, wherein the energy specific extraction kit includes: a second stripper assembly with a stripper located at a second stripping position for stripping charged particles at a second energy and an insert for modifying an orientation of the tubular channel to match the second extraction path such that the modified charged particles of second energy intercept the target holder.

Cyclotron for extracting charged particles at various energies

The invention relates to a method for producing a radioisotope, which method comprises irradiating a volume of radioisotope-precursor fluid contained in a sealed cell of a target using a beam of particles of a given current, which beam is produced by a particle accelerator. The target is cooled and the internal pressure in the sealed cell is measured. During the irradiation, the internal pressure (P) in the sealed cell is allowed to vary freely. The irradiation is interrupted or its intensity is reduced when the internal pressure (P) in the sealed cell departs from a first tolerated range defined depending on various parameters that influence the variation in the internal pressure in the sealed cell during the irradiation. These parameters for example comprise, for a given target, particle beam and radioisotope-precursor fluid: the degree of filling of the hermetic cell, the cooling power used to cool the given target, and the beam current (I). The invention also relates to an installation for implementing the method.

Process and installation for producing radioisotopes

The invention relates to a device () for producing radioisotopes by irradiating a target fluid using a particle beam (). This device comprises an irradiation cell () that includes a cavity () for receiving the target fluid. A non-cryogenic cooling device cools the walls of the cavity (). The cavity () has an inclined surface () downwardly delimiting the cavity () so as to evacuate the target fluid, which condenses on contact with the cooled walls, under gravity towards a metal foil () which closes off this cavity (). The inclined surface () intersects the plane formed by the metal foil (), making an acute angle (a) with said plane, so as to form with the metal foil () a wedge-shaped zone () capable of collecting, by gravity, the condensed target fluid.
