"High intensity means more data, and more data means greater discovery potential," he said in a statement.
The new record measured a level of luminosity of 467,000 billion billion billion -- 467 followed by 30 zeros -- per square centimeter per second, which corresponds to several million particle collisions per second.
Enhanced power boosts the odds of identifying extremely rare sub-atomic particles, especially the elusive Higgs boson, or 'God particle'.
Earlier experiments have found most of the tiny and ephemeral matter predicted by the so-called Standard Model of particle physics -- except the Higgs boson.
Many scientists believe only the 27-kilometer (16.8-mile), 3.9-billion-euro (5.2-billion-dollar) LHC may be powerful enough to detect it.
The current run of LHC experiments is set to continue through 2012, by which time it should be possible to determine if the Higgs boson truly exists, CERN said.
"There's a lot of excitement at CERN today, and a tangible feeling that we're on the threshold of new discovery," said Serge Bertolucci, CERN's Director for Research and Scientific Computing.
