Compact assembly for production of medical isotopes via photonuclear reactions

A system for producing medical isotopes, the system comprising:

• a) a collimator module with an upstream end and a downstream end comprising a solid collimator heat sink defining a radiotransparent channel extending from the upstream end to the downstream end, the channel having a diameter, wherein the upstream end receives a radiation beam having a first cross-section, and the radiation beam passes through the channel from the upstream end to the downstream end;
• b) a converter module comprising a converter positioned downstream of the collimator module, the converter module comprising a solid converter heat sink defining an aperture coaxial with the channel and terminating at a point proximal with the converter;
• and
• c) a target module positioned downstream of the converter module, the target module comprising a target having a second cross-section and coaxially aligned with the channel and the aperture, wherein a front face of the target that faces the downstream end of the collimator module has a circular area with a diameter equal to the diameter of the channel, and a solid target heat sink in thermal communication with the target.
