Recycling antiprotons

Physicists at the Fermi National Accelerator Laboratory at  in the US are taking a new approach to satisfy their ever-increasing demand for antimatter: they will recycle antiprotons. To maximize the use that experiments can get out of the antimatter created at the lab, a storage ring, the Recycler, will keep hold of antiprotons that have survived many hours in the proton-antiproton collider, the Tevatron. When the collider experiments receive their subsequent batch of antiparticles, the beam will contain recycled antiprotons. This image shows the magnets of the Recycler Ring (green) suspended from the ceiling above the magnets (blue and red) of the Main Injector, which accelerates protons and antiprotons before they proceed for final acceleration in the Tevatron.
