Development of an ECR ion source with a high ionization efficiency

Sheikh, Shaheen Anwar January 1989 (has links)
Separation of rare or expensive isotopes, whether radioactive or stable, requires a high efficiency of the separation process. Electromagnetic isotope separation is the most widely-used of all separation processes. Its separation efficiency depends mainly upon the ionization efficiency of its ion source. An Electron Cyclotron Resonance (ECR) ion source has been developed for the separation of both stable and radioactive isotopes on account of its high ionization efficiencies. The maximum ionization efficiencies achieved with the ECR ion source for singly charged ions for a range of materials were: radioiodine (8%), carbon (10%), nitrogen (26%), oxygen (53%), neon (31%) and xenon (83%). A computer code ECREFF, based on the atomic processes which occur in the plasma, is described for the calculation of the ionization efficiency of an ECR ion source. The experimental and calculated data are compared.

SOLID TARGET SYSTEM FOR USE ON AN 11 MeV CYCLOTRON

Williamson, Andrew Carl 01 December 2010 (has links)
Molecular imaging is becoming an important contributor to the development of personalized medicine. Positron Emission Tomography (PET) is a technology that enables molecular imaging by allowing a physician to detect and map the location of various physiological processes. The purpose of this work is to design, fabricate and test a mechanism that would make the production of the PET isotope, copper-64 practical for both researchers and commercial suppliers. In order to have the maximum usefulness, the design needs to fit and operate within several constraints. A one dimensional thermal analysis indicated that operation of the system under existing cooling conditions would be a reasonable solution. Based on the design specifications, a detailed design was completed and fabricated. The design was functionally and operationally tested with the performance meeting expectations. The design was utilized to produce copper-64 isotope with a typical one hour bombardment producing 30 mCi of isotope. The design could be optimized if future isotope demand exceeded current production capacity or if research required the production of other radioisotopes with varying thermal characteristics.
