Brookhaven National Laboratory

…Relativistic Heavy Ion Collider at Brookhaven National Laboratory in Upton, New York, used a billion collisions between gold ions to create 18 instances of the heaviest antiatom, the nucleus of antihelium-4, which consists of two antiprotons and two antineutrons. Since antihelium-4 is produced so rarely in nuclear collisions, its detection…

…to manage the then new Brookhaven National Laboratory at Upton, Long Island, N.Y., for the Atomic Energy Commission. Brookhaven, now funded by the U.S. Department of Energy, carries out experiments in nuclear physics, chemistry, engineering, biology, and medicine. AUI was later chosen by the U.S. National Science Foundation to manage…

At the Brookhaven National Laboratory in Upton, N.Y., the Relativistic Heavy Ion Collider (RHIC) came into operation in 2000. This has two rings of magnets that cross to accelerate beams of gold ions to 50 GeV and then bring them into head-on collision. The aim is to…

…in an oak-pine forest at Brookhaven National Laboratory in central Long Island, New York, U.S., using ionizing radiation. A single radiation source was used in the center of the forest. The exposure, begun in the fall of 1961, was sufficient within months to eliminate all plants from a central area…

…33-GeV proton synchrotron at the Brookhaven National Laboratory in Upton, N.Y., and the 28-GeV machine at the European Organization for Nuclear Research (CERN), near Geneva.

…was the 3-GeV Cosmotron at Brookhaven. It, and other accelerators that soon followed, had weakly focusing magnets. The 28-GeV proton synchrotron at CERN and the 33-GeV machine at Brookhaven made use of the principle of alternating-gradient focusing, but not without complications. Such focusing is so strong that the time required…
