title: A simple thick target for production of89Zr using an 11MeV cyclotron.
abstract: The growing interest but limited availability of89Zr for PET led us to test targets for the89Y(p,n) reaction. The goal was an easily constructed target for an 11MeV Siemens cyclotron. Yttrium foils were tested at different thicknesses, angles and currents. A 90° foil tolerated 41µA without damage and produced ~800 MBq/h, >20mCi, an amount adequate for radiochemistry research and human doses in a widely available accelerator. This method should translate to higher energy cyclotrons.
