Antiproton Collector
Appearance
The Antiproton Collector (AC) was part of the antiparticle factory at CERN designed to decelerate and store antimatter, to study the properties of antimatter and to create atoms of antihydrogen. It was built in 1986 around the existing Antiproton Accumulator to improve the antiproton production by a factor of 10.
Low energy antiproton research continues at CERN using the Antiproton Decelerator. It was built as a successor to LEAR and started operation in 2000.
