Dense Plasma Focus for Isotopes Activation, C. Xiao, R.A. Behbahani, Sean Wolfe (Plasmionique Inc.), A. Hirose, University of Saskatchewan -- A dense plasma focus (DPF) device (DPF-UofS) has been designed and is being fabricated and assembled at the University of Saskatchewan for production of short-lived radioisotopes utilizing the energetic ion beam emitted from DPF. Since the short-lived isotopes must be produced in proximity of treatment or diagnostic facilities such as PET (Positron Emission Tomography), DPF is a promising cost-effective and more portable alternative to cyclotron facilities. DPF-UofS will be formed by discharging a capacitor bank (30 kV, 4.5 μF) through a pair of coaxial electrodes. The Lee Model has been used to optimize the design of DPF-UofS. A maximum ion beam fluence of about 10^15 ions per shot, beam energy of 20 J has been predicted. For the 12C(d,n)13N reactions, the estimated radioactivity of 13N (half lifetime is about 10 minutes) is about 1 kBq per shot. To achieve the desired radioactivity, high capacitor bank energy and high repetition rate is required.
The research is supported by CCNI, NSERC and CRC.
