Atom-smasher sets energy record

The European Organisation for Nuclear Research (CERN) says its Large Hadron Collider has "become the world's highest energy particle accelerator, having accelerated its twin beams of protons to an energy of 1.18 TeV in the early hours of the morning".

A teraelectronvolt (TeV) is equivalent to the kinetik energy level of a flying mosquito, but the collider squeezes this energy into a much smaller space.

CERN wants to ultimately achieve a maximum power of 7.0 teraelectronvolts in its bid to replicate the conditions immediately after the big bang.

The previous world record was set by a the US Fermi National Accelerator Laboratory's Tevatron collider in 2001, when it reached 0.98 TeV.

Scientists are looking to the collider - inside a 27-kilometre tunnel straddling the Franco-Swiss border near Geneva - to mimic the conditions that followed the Big Bang and help explain the origins of the universe.

The LHC was relaunched on November 20, after breaking down nine days after it was started with great fanfare in September 2008.

By next year, the LHC should be ramped up to 3.5 teraelectronvolts, reaching "close to five" teraelectronvolts in the second half of next year, scientists said.

"Already with 3.5 TeV, we can open new windows into physics. That can already happen next year," CERN director-general Rolf-Dieter Heuer had said.

At the same time, he would not predict how soon new data could be generated from the LHC, stressing that "it depends on how kind nature is to us".

The LHC at CERN took nearly 20 years to complete, at a cost of six billion Swiss francs ($6.5 billion).

The massive experiment aims to resolve physics enigmas such as an explanation for "dark matter" and "dark energy" that account for 96 per cent of the cosmos and whether other dimensions exist parallel to our own.

The Holy Grail will be finding a theorised component called the Higgs Boson, which would explain how particles acquire mass. The elusive Higgs has been dubbed the "God particle".
