Description

A target system has been developed for producing and extracting 13N (t1/2 ~10 minutes) using the 400 keV Van de Graaff accelerator in the Minnesota State University Applied Nuclear Science Lab in Mankato. Radiolabeled 13N compounds are commonly used for physiological imaging using Positron Emission Tomography (PET), a quantitative nuclear technique. 13N is produced in the 12C(d,n)13N reaction by irradiating our custom graphite target with a 400 keV deuteron beam.. The carbon target is then heated by an electric current to release the nitrogen isotope while simultaneously passing a suitable reaction gas though the target apparatus to extract the 13N from the carbon matrix. Our research this year has aimed to discover the impact that the deposition depth has on the extraction of the 13N. The proposed method to accomplish this was to change the angle of beam incidence. Although the amount produced is insufficient for imaging work, the theory and procedure may be applied at higher energy laboratories, capable of a greater yield reaction such as 13C(p,n)13N.
