The production of high-value medical isotopes such as ⁶⁸Ge、²²⁵Ac and ⁶⁷Cu presents a significant technical challenge. These isotopes possess low reaction cross-sections, resulting in inherently low production efficiency. To meet the growing clinical and commercial demand for these critical radionuclides, high-power, high-current particle beams are essential. However, operating under such intense beam conditions places extreme thermal and mechanical stress on the target, demanding exceptional stability in the target fabrication process and a highly robust engineering design for the entire station.
LBT has developed the High Current Solid Target Station to directly address this challenge. Leveraging our extensive experience in solid target system development, this station is specifically engineered to handle high-current particle beams reliably. It is a fully automated, remotely operated, and robust system designed for the large-scale production of novel and established medical isotopes.

Target preparation

Internal Target Station

While H^- beams are highly effective, the use of positive ion beams—such as D+ and He⁺⁺—unlocks access to a broader and more diverse range of medical and research isotopes. These beams enable nuclear reactions that protons cannot efficiently trigger, significantly expanding the portfolio of radionuclides available for applications in targeted therapy, diagnostic imaging, and scientific research.

Recognizing this potential, LBT has developed its specialized Internal Target Station for positive ion irradiation. The internal target configuration ensures optimal beam utilization and maximizes reaction efficiency, which is critical for achieving high yields of novel isotopes like ²¹¹At
