Dealing With Data

16th January 2014 – In the first run of the Large Hadron Collider, almost a billion proton-proton collisions took place every second in the centre of the ATLAS detector. That amounts to enough data to fill 100,000 CDs each second. If you stacked the CDs on top of each other, in a year it would reach the moon four times. Only a small fraction of the observed proton–proton collisions have interesting characteristics that might lead to discoveries. How does ATLAS deal with this mountain of data?

Higgs into fermions

26th November 2013 – The ATLAS experiment released preliminary results on 26 Nov 2013 that show evidence, with a significance of 4.1 standard deviations that the Higgs boson decays to two taus, which are fermions. This is exciting news. But what makes this measurement important?

Full Coverage for ATLAS Muons

29th October 2013 – Hold out your hand and in one minute hundreds of muons will have passed through your palm. Muons are one of the high-energy cosmic ray particles that can pass through most solid structures – even the ATLAS detector’s calorimeter, which is designed to absorb particles and measure their energy. A specific system is required to measure muons. Until now, the ATLAS muon system was almost completed, but not quite. The last of the 62 chambers in the Extended Endcap (EE) region was installed just before summer this year.

Crowds at ATLAS for CERN Open Days

2nd October 2013 – More than 70,000 people visited CERN Open Days over the weekend, with 20,000 going underground to see the LHC tunnel and the detectors. Of these, an estimated 5,000 people visited the ATLAS exhibits aboveground, and another 2,500 had the opportunity to see the ATLAS detector.

High-flying physics

11th September 2013Pernilla Craig earned her licence to fly last year aged just 17, making her one of UK’s youngest female pilots. A visit to CERN last week took her deep underground to see dectectors on the Large Hadron Collider (LHC), and into the sky above the Alps for a bird's eye view of the laboratory.
