Patent ID: 8288736

Claim:
An irradiation cell for producing a radioisotope of interest through the irradiation of a target material by a particle beam, the irradiation cell comprising a target body, a diffuser configured to provide a path for a cooling medium, and a removable metallic insert comprising a cavity designed to house the target material and the cavity closed by an irradiation window, the metallic insert configured to be inserted in and removed from the target body, wherein the removable metallic insert comprises at least two separate metallic parts of different materials, the metallic insert comprising at least a first part and a second part, the first part having a wall with a thickness between 0.3 and 0.7 mm and an elongated cavity surrounded by the wall, the cavity being longer in a direction parallel to the particle beam that irradiates the target than in a direction perpendicular to the particle beam, and the second part partially surrounding the first part and forming a channel configured to guide a cooling medium, the first part being removable from the irradiation cell without removal of the second part by sliding the first part in a direction parallel to the particle beam.
