Later in the article: "'Once we’ve exhausted our exploration of the data, we see no reason not to make them available publicly,' said CMS physicist Kati Lassila-Perini, who leads the detector's data-preservation efforts."

"If you ever wanted to take a look at raw data produced by the Large Hadron Collider, but are missing the necessary physics PhD, here's your chance: CERN has published more than 300 terabytes of LHC data online for free. The data covers roughly half the experiments run by the LHC's CMS detector during 2011, with a press release from CERN explaining that this includes about 2.5 inverse femtobarns of data — around 250 trillion particle collisions. Best not to download this on a mobile connection then."
