Abstract
Target assembly for an isotope production system. The target assembly includes a target body having a production chamber and a beam cavity that is adjacent to the production chamber. The production chamber is configured to hold a target material. The beam cavity is configured to receive a particle beam that is incident on the production chamber. The target assembly also includes a target foil positioned to separate the beam cavity and the production chamber. The target foil has a side that is exposed to the production chamber such that the target foil is in contact with the target material during isotope production. The target foil includes a material layer having a nickel-based superalloy composition.

A target assembly for an isotope production system, the target assembly comprising:
- a target body having a production chamber and a beam cavity that is adjacent to the production chamber, the production chamber configured to hold a target material, the beam cavity being configured to receive a particle beam that is incident on the production chamber;
- and
- a target foil positioned to separate the beam cavity and the production chamber, the target foil having a side that is exposed to the production chamber such that the target foil is in contact with the target material during isotope production, wherein the target foil includes a material layer having a nickel-based superalloy composition, wherein the nickel-based superalloy composition includes at least 40 wt % nickel and a sum of percent weights for aluminum and titanium is at most 10 wt %.
A method of generating radionuclides, the method comprising:
- providing a target material into a production chamber of a target assembly, the target assembly having a production chamber and a beam cavity that is adjacent to the production chamber, the production chamber configured to hold a target fluid, the beam cavity configured to receive a particle beam that is incident on the production chamber, the target assembly also including a target foil positioned to separate the beam cavity and the production chamber, the target foil having a side that is exposed to the production chamber such that the target material is in contact with the target foil during isotope production, wherein the target foil includes a material layer having a nickel-based superalloy composition;
- and
- directing the particle beam onto the target material, the particle beam passing through the target foil to be incident on the target material, wherein a beam current of the system is at least 100 μA.
A target assembly for an isotope production system, the target assembly comprising:
- a target body having a production chamber and a beam cavity that is adjacent to the production chamber, the production chamber configured to hold a target material, the beam cavity being configured to receive a particle beam that is incident on the production chamber;
- and
- a target foil positioned to separate the beam cavity and the production chamber, the target foil having a side that is exposed to the production chamber such that the target foil is in contact with the target material during isotope production, wherein the target foil includes a material layer having a nickel-based superalloy composition;
- wherein the target foil includes a nickel-based superalloy layer and a secondary layer that is stacked with respect to the nickel-based superalloy layer, the secondary layer being positioned between the nickel-based superalloy layer and the production chamber and exposed to the production chamber such that the target material is in contact with the secondary layer during isotope production, wherein the secondary layer comprises refractory or platinum-group metals or alloys thereof.
