Fused Zinc Target for the Production of Gallium RadioisotopesDOI: https://doi.org/10.3390/instruments3010010 Keywords: PET, medical isotopes, Ga-68, solid target Abstract: Abstract Gallium-68 is a popular radioisotope for positron emission tomography. To make gallium-68 more accessible, we developed a new solid target for medical cyclotrons. Fused zinc targets promise a new, efficient, and reliable technique without the downsides of other commonly used time-consuming methods for solid target fabrication, such as electroplating and sputtering. We manufactured targets by fusing small pressed zinc pellets into a recess in aluminum backings. Using a simple hotplate, the fusing could be accomplished in less than two minutes. Subsequently, the targets were cooled, polished, and used successfully for test irradiations at Ep = 12.8 MeV and up to 20 μA proton current. View Full-Tex
