    Two-thirds in common: AMS and CMS

    The Alpha Magnetic Spectrometer (AMS) experiment, designed to study dark matter and anti-matter from the International Space Station, launched successfully aboard the Endeavour shuttle from NASA’s Kennedy Space Center on 16th May, 2011. AMS was built by an international collaboration of 600 physicists from 56 institutes including CERN and a few CMS institutes.

  • Splash Events (6th-7th November)

    On the weekend of 6th & 7th November the LHC beam was injected and arrived near the CMS experiment, before being “stopped” by a large amount of material known as a “collimator”.
