Large quantities of separated isotopes are needed for rare particle and rare decay detection in basic nuclear physics research. The demand for these isotopes cannot be met by existing inventory or through foreign supplies. Meanwhile, existing isotope separation technologies have limitations in cost and quantity. Therefore, this project will develop a next generation isotope separation technology, the Integrated Spin System (ISS), for producing large quantities of stable isotopes efficiently and economically. In Phase I, proof-of-concept was demonstrated experimentally through the separation of different gas species and gaseous isotopes. Engineering data showed that the ISS was adept in separating metallic isotopes directly, without the use of chemicals. In Phase II, a detailed engineering prototype will be designed and constructed, and the separation of large quantities of Ge-76, Xe-136 and other isotopes will be demonstrated.
Commercial Applications and Other Benefits as described by the awardee: The use of stable isotopes is strategically important to the U.S., encompassing broad areas of scientific research, medical applications, and industries. The ISS would establish the first domestic stable isotope supply center and would insulate the country from geopolitical influences on foreign supplies
