U.S. and European officials today signed an agreement for U.S. participation in the Large Hadron Collider, a particle accelerator under construction near Geneva, Switzerland.

In a ceremony on Monday morning, September 15, officials at the Department of Energy’s Fermi National Accelerator Laboratory will mark the end of one era in frontier particle physics research at the laboratory and the beginning of another.

Experimenters at Fermi National Accelerator Laboratory announced at the Laboratory’s weekly All-Experimenters’ Meeting on November 18, 1996, that they had begun to detect atoms of antihydrogen produced in a gas-jet target in the Fermilab Antiproton Accumulator.

At a collaboration meeting in San Rafael, Argentina, scientists of the Pierre Auger Project, whose goal is to discover the source of very high-energy cosmic rays, today (September 13) announced the choice of the project’s northern-hemisphere observatory.

Scientists of the Pierre Auger Project, whose goal is to discover the source of very high-energy cosmic rays, will announce the choice of the project’s northern-hemisphere observatory at a meeting in San Rafael, Argentina on September 12. The 150-member collaboration will choose among three sites: one in western Spain, one in the western U.S., and one in Mexico.

An article to appear in the February 9 issue of Science describes results contained in a paper submitted to Physical Review Letters by the 450-member Collider Detector at Fermilab collaboration.

As cool weather and warm colors herald autumn’s arrival, the Department of Energy’s Fermi National Accelerator Laboratory, in keeping with a fall tradition, is offering area residents a chance to join in the Laboratory’s annual Prairie Seed Harvest, scheduled for Oct. 7th and 28th.

Batavia IL — Physicists at the Department of Energy’s Fermi National Accelerator Laboratory today (March 2) announced the discovery of the subatomic particle called the top quark, the last undiscovered quark of the six predicted by current scientific theory. Scientists worldwide had sought the top quark since the discovery of the bottom quark at Fermilab in 1977. The discovery provides strong support for the quark theory of the structure of matter. Two research papers, submitted in Friday, February 24, to…
