Cern's LHC breaks beam intensity record again

Summary: The Large Hadron Collider has retaken the crown of the world's most intense beam producer, although the facility says reports of it discovering the Higgs boson remain premature

Cern's Large Hadron Collider has set a new world record for beam intensity, meaning the massive experiment can record more data than before.

According to the European nuclear research facility, the Large Hadron Collider (LHC) now collides beams with a luminosity of 4.67x1032cm-2s-1, breaking the 4.024x1032cm-2s-1 record set in 2010 by the Tevatron at the Fermi National Accelerator Laboratory in the US. That record had in turn broken another set by Cern in 2009.

"Beam intensity is key to the success of the LHC, so this is a very important step," Cern director-general Rolf Heuer said in a statement on Friday. "Higher intensity means more data, and more data means greater discovery potential."

Higgs boson search

The LHC is a giant experiment, involving a 27km ring tunnel buried deep beneath the Alps, that aims to recreate the conditions immediately after the Big Bang. One of the things Cern hopes to find is the Higgs boson: the particle's existence would prove some of the fundamental theories of physics.

According to Cern, the current run of the LHC will continue until the end of 2012 at its current energy of 3.5 tera-electron-volts (TeV), after which it will be readied for a run at its full energy of 7 TeV per beam. The current run should be enough to ascertain the existence or otherwise of the Higgs boson.

"There's a great deal of excitement at Cern today and a tangible feeling that we're on the threshold of new discovery," the organisation's research and scientific director, Sergio Bertolucci, said in the statement.

However, a spokeswoman for the facility told ZDNet UK on Tuesday, rumours that the Higgs boson have already been found are premature. These rumours are based on a leaked Cern memo, but the spokeswoman said this was "just a pre-memo" that has not even passed the scrutiny of the Atlas collaboration team that is running the experiment.

"Somebody has leaked it [but] often these results go away because they don't withstand the tests," Cern's spokeswoman said.

  • The discovery of gravity’s exact mechanism along with that of dark matter has already taken place, way back in autumn 2010. I know from my theoretical understanding that it is impossible to find any traces of Higgs boson as a quantum particle in the Hadron collider, neither can it show the existence of dark matter. The details of my discovery of how gravitation exactly works, http://www.anadish.com/ , and how it is produced in the framework of quantum mechanics are lying in wraps with the USPTO and I can only make it entirely public after there is clarity on how the USPTO is going to settle the issue of secrecy on my application. I consciously did not report to any peer-reviewed journal, fearing discrimination, because of my non-institutional status as a researcher. However, if the USPTO also continues with their non-committal secrecy review under LARS Level 2 (find the PDF of Private PAIR of the USPTO on my site), then, anyway, my discovery may not get published for a long time to come, in spite of me having filed the US patent application (US 13/045,558) on March 11, 2011, after filing a mandatory Indian patent application on January 11, 2011. Till, I find a clue to come out of the maze of government regulations, unless, of course, the USPTO decides to put it out of secrecy.

  • Thanks for letting us know Anadish - it is always enjoyable to read about the secrecy of secret discoveries being kept secret by secret entities who do everything in secret and go to great lengths to keep their secrets as secrets.

  • However, the United States Patent and Trademark Office (USPTO) is not a secret entity at all, neither am I.
