Today it’s exactly twelve years that I have my CERN account :)
I first got it on 8 March 2005 when starting my internship in the high-energy-physics group at the Niels Bohr Institute in Copenhagen, thereby laying the foundation of all that came afterwards … great people, great physics, great places … looking forward to more of all :)
Based on the submission date of the Letter of Intend, 1 October 1992, the ATLAS Experiment will turn 25 years this autumn and I will have the pleasure to organise a live event on the actual birthday as well as an internal celebration during the Bratislava ATLAS Week in October … while getting caught in this, I noticed that, based on this calculation, I have been with ATLAS for half of its life (and a third of mine) by then.
We had Christmas dinner at work yesterday … more than two kilograms of cheese (Appenzeller, Gruyère, Emmental and an old Tyrol cheese) in seven different kinds of cheese fondue (Appenzeller, Gruyère, Tyrol, tomato mixed, spring onion mixed, bacon mixed, chives mixed; and yes, I know it’s eight caquelons) for about 40 group members. Certainly an experience … from shopping, over preparation, to the dinner itself :)
Today Maarten Boonekamp, whom I had the pleasure to work with for my master thesis, presented the latest update on the measurement of the W-boson mass with ATLAS. In fact a subject I wrote part of thesis about and had my name on a physics paper for the first time. Not yet the precision predicted in the paper, but it’s also not yet the stats and certainly not the centre-of-mass energy assumed therein. Yet it’s a competitive measurement (80.370 GeV ± 0.019 GeV) in full agreement with the Standard Model.
