9-May-2016 Large Hadron Collider prepares to deliver 6 times the data
After months of winter hibernation, the Large Hadron Collider is once again smashing protons and taking data. The LHC will run around the clock for the next six months and produce roughly 2 quadrillion high-quality proton collisions, six times more than in 2015 and just shy of the total number of collisions recorded during the nearly three years of the collider's first run.
26-Apr-2016 The hottest job in physics?
While the supply of accelerator physicists in the United States has grown modestly over the last decade, it hasn't been able to catch up with demand fueled by industry interest in medical particle accelerators and growing collaborations at the national labs.
7-Apr-2016 Physicists build ultra-powerful accelerator magnet
The next generation of cutting-edge accelerator magnets is no longer just an idea. Recent tests revealed that the United States and CERN have successfully co-created a prototype superconducting accelerator magnet that is much more powerful than those currently inside the Large Hadron Collider.
6-Apr-2016 Six weighty facts about gravity
Gravity: we barely ever think about it, at least until we slip on ice or stumble on the stairs. To many ancient thinkers, gravity wasn't even a force -- it was just the natural tendency of objects to sink toward the center of Earth, while planets were subject to other, unrelated laws.
4-Apr-2016 Putting it all together: Fermilab assembles first cryomodule for LCLS-II
In February, a Fermilab team came together to witness a moment they'd looked forward to for over a year. Crew members parted the plastic sheeting at one end of a cleanroom and rolled out on narrow tracks a long string of eight accelerating cavities. It was the first cavity string for LCLS-II, which will greatly increase the power and capacity of SLAC's Linac Coherent Light Source.
21-Mar-2016 Bump in LHC data has physicists electrified
In December, the ATLAS and CMS experiments reported what could be the first hint of a new massive particle that spits out two photons as it decays. Now, physicists are presenting their latest analyses at the Moriond conference in La Thuile, Italy, including a full investigation of this mysterious bump. After carefully checking, cross-checking and rechecking the data, both experiments have come to the same conclusion -- the bump is still there.
25-Feb-2016 Fermilab scientists discover new 4-flavor particle
Scientists on the DZero collaboration at the US Department of Energy's Fermilab have discovered a new particle -- the latest member to be added to the exotic species of particle known as tetraquarks.
17-Feb-2016 Scientists start small on the road to building gigantic DUNE neutrino detector
The planned Deep Underground Neutrino Experiment will require 70,000 tons of liquid argon, making it the largest experiment of its kind -- 100 times larger than the liquid-argon particle detectors that came before it. Before building this unprecedented machine, scientists understandably want to make sure it's going to work. That's why members of the international DUNE collaboration recently began taking data using a test version of their detector.
3-Feb-2016 A mile-deep campus
Students at South Dakota universities can study physics at Sanford Underground Research Facility, which doubles as essentially the first college campus located a mile underground.
28-Jan-2016 Is the neutrino its own antiparticle?
Almost every particle has an antimatter counterpart: a particle with the same mass but opposite charge, among other qualities. But certain characteristics of neutrinos and antineutrinos make scientists wonder: Are they one and the same? Are neutrinos their own antiparticles?
25-Jan-2016 How to find and study black holes
Black holes sound too strange to be real. But they are actually pretty common in space. There are dozens known and probably millions more in the Milky Way and a billion times that lurking outside. The makings and dynamics of these monstrous warpings of spacetime have been confounding scientists for centuries.
22-Apr-2015 ICARUS neutrino experiment to move to Fermilab
A group of scientists led by Nobel laureate Carlo Rubbia will transport the world's largest liquid-argon neutrino detector across the Atlantic Ocean to its new home at the US Department of Energy's Fermi National Accelerator Laboratory.
6-Oct-2014 Fermilab's 500-mile neutrino experiment up and running
It's the most powerful accelerator-based neutrino experiment ever built in the United States, and the longest-distance one in the world. It's called NOvA, and after nearly five years of construction, scientists are now using the two massive detectors -- placed 500 miles apart -- to study one of nature's most elusive subatomic particles.
31-Jul-2014 Giant electromagnet completes its journey, moves into its new home at Fermilab
One year ago, the 50-foot-wide Muon g-2 electromagnet arrived at the US Department of Energy's Fermi National Accelerator Laboratory in Illinois after traveling 3,200 miles over land and sea from Long Island, N.Y. This week, the magnet took the final few steps of that journey, moving across the Fermilab site and into the new building that now houses it.
25-Jun-2014 Massive 30-ton MicroBooNE particle detector moved into place, will see neutrinos this year
On Monday, June 23, the next phase of neutrino physics at Fermilab fell (gently) into place.
The MicroBooNE detector -- a 30-ton, 40-foot-long cylindrical metal tank designed to detect ghostly particles called neutrinos -- was carefully transported by truck across the US Department of Energy's Fermilab site, from the warehouse building it was constructed in to the experimental hall three miles away.
6-Jun-2014 MINOS result narrows field for sterile neutrinos
A new result from the long-running MINOS experiment announced this week severely limits the area in which sterile neutrinos could be found and casts more doubt on whether they exist at all.
8-May-2014 Scientists to map universe in 3-D HD
In a few years, scientists will come out with a new map of a third of the sky, one that will go deeper and bring that depth into sharper focus than any survey has yet achieved. It will pinpoint in three dimensions the locations of 25 million galaxies and quasars, pulling back the curtains on the history of the universe's expansion over more than half of the age of the universe.
29-Apr-2014 Is the universe balanced on a pinhead?
Scientists have known the mass of the heaviest fundamental particle, the top quark, since 1995. But recent, more precise measurements of this mass have revived an old question: Why is it so huge? No one is sure, but it might be a sign that our universe is inherently unstable. Or it might be a sign that some factor we don't yet understand is keeping us in balance.
1-Mar-2014 CDMS result covers new ground in search for dark matter
Scientists looking for dark matter face a serious challenge: No one knows what dark matter particles look like. So their search covers a wide range of possible traits -- different masses, different probabilities of interacting with regular matter.
Today, scientists on the Cryogenic Dark Matter Search experiment, or CDMS, announced they have shifted the border of this search down to a dark-matter particle mass and rate of interaction that has never been probed.
10-Nov-2009 An electron zap turns flimsy plastic into sturdy shrink wrap
If you buy a Butterball turkey this Thanksgiving, you have particle accelerators to thank for its freshness. For decades now the food industry has used particle accelerators to produce the sturdy, heat-shrinkable film that Butterballs come wrapped in.
16-Jul-2009 Dark Energy Camera scans ancient skies
Scientists wonder why the universe is expanding ever faster. What mysterious force is at work? By recording the light from hundreds of millions of galaxies from a mountaintop in Chile, they hope to find out what's going on.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
