Apparatus for producing a radioisotope comprising means for maintenance and method of maintenance for said apparatus

摘要

The present invention relates to an apparatus for producing a radioisotope by irradiating a target fluid comprising a precursor of said radioisotope with a particle beam produced by a particle accelerator, the apparatus comprising:
€¢ a housing comprising a target cavity for receiving said target fluid, said housing having an opening for allowing the passage of the said particle beam into the said cavity;
€¢ a dual foil flange for closing said opening of the target cavity, said dual foil flange comprising :
- a standoff comprising a central hole;
- a first and a second foil able to allow the passage of the said particle beam and located respectively on a first side and a second side of the said standoff, covering the said central hole and forming a cooling cavity;
- a first flange and a second flange for sealing respectively the said first and second foil on said standoff;
- at least an inlet channel and at least an outlet channel, for flowing a cooling fluid through the cavity of the dual foil flange;
€¢ guiding means for positioning said dual foil flange in an in-line position in which a said foil is facing said opening of said housing.
