Officials at the European Organization for Nuclear Research (CERN) have created the highest energy levels yet achieved in a particle accelerator, recording a pair of 3.5 trillion electron volts (TeV) beams in their Large Hadron Collider (LHC) early Friday Morning. The 3.5 TeV readings are three-times larger than any achieved by a man-made device. CERN officials are calling it "an important step" in their research, during which they will try to recreate conditions similar to those found during...

A worldwide team of researchers, including 10 from Texas A&M University, have for the first time created a particle that is believed to have been in existence immediately after the creation of the universe "“ the so-called "Big Bang" "“ and it could lead to new questions and answers about some of the basic laws of physics because in essence, it creates a new form of matter. Researchers Carl Gagliardi, Saskia Mioduszewski, Robert Tribble, Matthew Cervantes, Rory Clarke, Martin...

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory in New York report they have created the hottest temperature in the lab -- 4 trillion degrees Celsius -- which is thought to be consistent with actual temperatures that existed when the universe was born. The Relativistic Heavy Ion Collider (RHIC) was used to smash gold ions together to make super-heated explosions that lasted only milliseconds. RHIC is a particle accelerator that is 2.4 miles around and is buried...

CERN's Large Hadron Collider set a new record this week in its quest to recreate Big Bang conditions and allow scientists to gain a better understanding of the nature of matter, Reuters reported. Now, CERN plans to shut the collider down for a few months in order to get ready for even higher energy work. "This first running period has served its purpose fully: testing all the LHC's systems, providing calibration data for the experiments and showing what needs to be done to prepare the machine...

The largest atom smasher in the world has caught its first high-energy collision of protons, CERN announced on Wednesday. Physicists are hoping that these collisions will give them better insight into phenomena like dark matter and antimatter. They also believe it will ultimately help them understand the beginning of the universe billions of years ago, which many believe is the result of a massive explosion known as the Big Bang, reported the Associated Press. The collisions were...

According to the European Organization for Nuclear Research, the Large Hadron Collider (LHC) is expected to be restarted by this weekend after over a year of repairs. Spokesman James Gillies says scientists have refrained from setting an exact date for sending beams of protons around the 17-mile circular tunnel housing the world's largest atom smasher. Gillies says the organization known as CERN is taking its time with the sophisticated equipment. The LHC was launched last year before...

A time-varying bubble of electron density in the wake of an ultra-intense laser pulse traps the ambient plasma electrons and accelerates them to high energy producing collimated monoenergetic beams for medical, technological, and physics applications. ATLANTA"”Particle accelerators are among the largest and most expensive scientific instruments. Thirty years ago, theorists John Dawson and Toshiki Tajima proposed an idea for making them thousands of times smaller: surf the particles on...

Scientists leverage special relativity to speed up computational modeling and open a new era for designing advanced laser-plasma accelerators Using Einstein's theory of special relativity to speedup computer simulations, scientists have designed laser-plasma accelerators with energies of 10 billion electron volts (GeV) and beyond. These systems, which have not been simulated in detail until now, could in the future serve as a compact new technology for particle colliders and energetic light...

Engineers have successfully injected beams of particles into two sections of the Large Hadron Collider (LHC), marking the first time particle beams have been inside the LHC since it was shut down in September 2008, BBC News reported. Scientists working on the giant particle accelerator called it "a milestone" and plan to circulate a beam around the 16 mile-long tunnel in November. Last year, a magnet problem called a "quench" caused the LHC to leak a ton of liquid helium, forcing it to shut...

The Large Hadron Collider (LHC) experiment is now more frigid than deep space, making it one of the coldest locations in the Universe, BBC News reported. Recent adjustments in all eight sectors of the LHC have dropped the operating temperature to 1.9 kelvin (-271C; -456F). Liquid helium maintains the intense cold in nearly 17-mile long magnets that bend particle beams around the LHC.  The magnets are positioned end-to-end in a circular tunnel overlapping the Franco-Swiss border. The...
