Building 40 at CERN’s Meyrin site was abuzz with excitement as CMS formally inaugurated an art installation featuring a full-size high-resolution photograph of the CMS detector organised by the CMS Communications Group. The unveiling was met with…

This is a collaborative wiki where people write scrappers that can be re-used to trawl the internet or a specific website automatically and find data relating to a particular topic. For instance there is a scrapper that looks through twitter for…

Piazza is an online forum for ask and answer questions. Users ask a question that is then answered by other users and/or identified experts. There is only one space for each answer and answers are edited wiki-style, with versioning - so the forum…

Building 40 at CERN is going to change its appearance. A beautiful 1:1 maxi-poster of CMS is being installed in the central hall. To celebrate the completion of this installation we would like to invite you to a short drink this coming Friday from…

CMS is now running with 1236 bunches of protons !

This year's LHC physics run started in March. Since then the machine has broken many records, bringing its luminosity — the number of proton-proton collisions per second — to much higher levels than expected for this year. CMS now can take as much…

Christophe Delaere, from the Université catholique de Louvain in Belgium, has been with CMS for five years. Christophe works on the Tracker, the sub-detector that traces the path of charged particles that are formed in collisions at the LHC. Watch…

Record fill for CMS: recorded 35.5 pb-1 ("inverse picobarns") of collisions - almost as much as we recorded in the whole of 2010!

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…

After the success of the LHC restart in late 2009, the machine had its first Technical Shutdown over the Christmas period, lasting until the end of February. This time was used fruitfully, both by the accelerator and by CMS (see the first CMS Times…

On 14th December, just 3 weeks after its restart, the LHC collided 1.18TeV beams of protons in CMS for the first time. During this first period more than 15000 2.36 TeV collision events were accumulated by CMS. You can keep up with the excitement…
