Geneva, 17 November 2010. The ALPHA experiment at CERN1 has taken an important step forward in developing techniques to understand one of the Universe’s open questions: is there a difference between matter and antimatter? In a paper published in Nature today, the collaboration shows that it has successfully produced and trapped atoms of antihydrogen. This development opens the path to new ways of making detailed measurements of antihydrogen, which will in turn allow scientists to compare matter and antimatter.
Geneva, 8 November 2010. Four days is all it took for the LHC operations team at CERN1 to complete the transition from protons to lead ions in the LHC. After extracting the final proton beam of 2010 on 4 November, commissioning the lead-ion beam was underway by early afternoon. First collisions were recorded at 00:30 CET on 7 November, and stable running conditions marked the start of physics with heavy ions at 11:20 CET today.
Geneva, 4 November 2010. Proton running for 2010 in the LHC at CERN1 came to a successful conclusion today at 08:00 CET. Since the end of March, when the first collisions occurred at a total energy of 7 TeV, the machine and experiment teams have achieved all of their objectives for the first year of proton physics at this record energy and new ground has been explored. For the rest of the year the LHC is moving to a different phase of operation, in which lead ions will be accelerated and brought into collision in the machine for the first time.
Geneva, 6 October 2010. The ATLAS1 collaboration at CERN2 today officially unveiled a giant mural depicting the ATLAS particle detector, which is currently collecting data at the world’s most powerful particle accelerator, the Large Hadron Collider. Installed in a cavern 100 metres underground, the ATLAS detector is no longer open for visits. The mural, painted on the wall of an ATLAS surface building by American artist Josef Kristofoletti, is three storeys tall yet still one-third the size of the actual detector. The mural is designed to be the next best thing to seeing the detector itself.
Geneva, 17 September 2010. During an intense series of meetings, which concludes today, the CERN1 Council overwhelmingly approved the laboratory's revised Medium Term Plan for the period 2011 to 2015. The plan was originally presented to Council at its June session, at which Council asked CERN management to introduce cost-saving measures.
