Tevatron operations: A way of life

This afternoon, Sept. 30, Fermilab will shut down the Tevatron for the last time. This story honors the operators - the men and women who have kept the accelerators running 24 hours a day, seven days a week, 365 days a year. Continue reading

Fermilab’s Antiproton Source: A rich history and an exciting future

Fermilab’s Antiproton Source has long produced the antimatter that makes Fermilab’s particle collisions possible. While the Antiproton Source will shut down along with the Tevatron on Sept. 30, there are plans for its future. Continue reading

Tevatron shutdown eve

On the eve of the shutdown of Fermilab's Tevatron, collaborators from the CDF and DZero experiments are expressing their gratitude for all the hard work and dedication that made 26 years of capturing billions of proton and antiproton collisions possibl... Continue reading

LHC control centers open to teens for a night

On Friday Sept. 23, students arrived at control rooms for the LHC and its detectors throughout the evening in groups of five to 10. For the second time, members of the four largest experiments at the LHC at CERN were participating in Researchers’ Nig... Continue reading

OPERA experiment sees neutrinos seem to beat speed of light

The OPERA neutrino experiment announced today the kind of result that keeps a physicist up at night. Scientists revealed that they have observed subatomic particles seeming to travel faster than the speed of light. Leaders of the collaboration will sha... Continue reading

Developers create virtual CERN

Neng Xu, a software engineer for the University of Wisconsin-Madison working on the ATLAS experiment, sat drinking coffee in a sunny corner of CERN’s cafeteria when he thought of a challenge. Could he create a virtual version of what he saw out the w... Continue reading

Keeping the Tevatron’s cool: A look back at electron cooling

When electron cooling was implemented at Fermilab in 2005, scientists thought it could help increase the peak luminosity by a factor of 1.5 to 2. Now, less than a decade later, it has become integral to the Tevatron’s success, leading to an increase ... Continue reading

Particle accelerators used to compile nutritional database in Sudan

Forty-one percent of the children in Sudan are malnourished and underweight, according to the Food and Agriculture Organization of the United Nations. Mohamed Eisa, a physicist at the Sudan University of Science & Technology, would like to change ... Continue reading
