Physicists here at CERN love acronyms! Some of them are complete tongue-twisters (try pronouncing MWRG!), others sound not awfully bad (like CRUZET or CRAFT). Learning these fast is a big challenge for newcomers 🙂
Now, why do I write all this? Well, while sitting in a meeting I heard these three coming up in the discussion and felt a bit nostalgic. Last time I had heard them was in 2009 when we were again preparing for an LHC start up. Interesting times.
MWRG : Mid-Week Global Run (preparatory test runs performed weekly as detectors are being commissioned)
CRUZET : Cosmic RUn at ZEro Tesla (full CMS-wide test run with the magnet off, without beam, but looking at particles offered to us for free by cosmic radiation)
CRAFT : Cosmic Run At Four Tesla (full CMS-wide test run with the magnet ON, again using cosmic radiation particles)
