How did the Tevatron accelerate and collide protons with antiprotons?
The Tevatron at Fermilab functioned as a superconducting synchrotron that accelerated protons and antiprotons in counterrotating beams to approximately 1 TeV before colliding them.1
Proton Acceleration
Protons began as negative hydrogen ions, accelerated in a linear accelerator to 400 MeV. After a carbon foil stripped the electrons, the protons entered the Booster, reaching 8 GeV. They were then transferred to the Main Injector, which accelerated them to 150 GeV before injection into the Tevatron ring for final acceleration.1
Antiproton Production and Acceleration
Antiprotons were created by firing 120-GeV protons from the Main Injector at a nickel target. The resulting antiprotons were focused by a lithium lens, cooled in a debuncher, and stored in accumulator and Recycler rings. Once sufficient numbers were gathered, they were injected into the Main Injector, accelerated to 150 GeV, and transferred to the Tevatron.1
Once both beams reached maximum energy, they were stored and directed to collide at specific points around the ring where detectors captured the resulting particle interactions.1
