29th April 2014 – On 5 and 6 April, Michigan State University's ATLAS physicists who are based at CERN connected virtually via video-conference to visitors attending the annual Science Festival in East Lansing, USA, to talk about particle physics and what it is like to be a physicist.
13th February 2014 – The first recipients of the ATLAS PhD Grant were presented with a certificate on 11 February at CERN by the programme’s selection committee. The three scholars, Lailin Xu of China, Josefina Alconada of Argentina, and Gagik Vardanyan of Armenia, were delighted at being able to continue their PhD programmes at CERN.
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?
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?
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.
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.
23rd September 2013 – Only a few more days to go before CERN opens its doors and our universe becomes yours on 28 and 29 September. With 35 surface sites and seven underground visits available, there will be plenty of activities for visitors of all ages.
11th September 2013 – Pernilla Craig earned her licence to fly last year aged just 17, making her oneof 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.
