The growing interest but limited availability of Zr-89 for PET led us to test targets for the Y-89(p,n) reaction. The goal was an easily constructed target for an 11 MeV Siemens cyclotron. Yttrium foils were tested at different thicknesses, angles and currents. A 90 degrees foil tolerated 41 mu A without damage and produced 800 MBq/h, > 20 mCi, an amount adequate for radiochemistry research and human doses in a widely available accelerator. This method should translate to higher energy cyclotrons.
