In 1976, he suggested adapting CERN's Super Proton Synchrotron (SPS) to collide protons and antiprotons in the same ring and the world's first antiproton factory was built.
It takes the antiprotons from the antiproton decelerator and cools them to 90 KeV which is "cold" enough to study.
It was under his guidance that the original accelerator was replaced with the Tevatron, an accelerator capable of colliding proton and an antiproton at a combined energy of 1.96 TeV.
For example, the charges of a proton and antiproton must sum to exactly zero.
In 2016 a new antiproton decelerator and cooler called ELENA (E Low ENergy Antiproton decelerator) was built.
