1. A method for producing Mo-99 via neutron capture comprising:
disposing a fixture within a nuclear reactor, the fixture sized and configured to be exposed to a neutron field of the nuclear reactor, the fixture comprising a source material at least partially comprising Mo-98 target material, a positively charged anode providing a positive electric charge to the Mo-98 target material, a cathode collector spaced apart from the source material such that an environment is disposed between the cathode collector and the source material, a negatively charged cathode electrically coupled to the cathode collector to provide a negative electric charge to the cathode collector; and a vacuum port; and
creating a vacuum environment within the fixture, the vacuum environment including at least a portion of the environment disposed between the cathode collector and the source material;
wherein exposure of the Mo-98 target material to the neutron flux field of the nuclear reactor produces Mo-99 ions from the Mo-98 target material; and
wherein the cathode collector is configured to collect the Mo-99 ions.
