But first the antiprotons have to be manufactured. That means protons will come from the Main Injector and transfer to the Main Ring Remnant, exit at F 17 and head to the Antiproton Source; their numbers stack up in the Accumulator before they return to the Tevatron via the Main Ring Remnant and FZero. “We can’t get beam into the Tevatron without FZero,” Sauer explained.
