18th November 2011 – I’m writing from the annual Hadron Collider Physics Symposium, which began on Monday in Paris, France. It’s organised jointly by LPNHE and the University of Paris VI & VII, with an excellent location right in the heart of the Latin Quarter. HCP is a fun conference with only plenary talks, which means that I’ve had the chance to attend talks on a wide range of subjects including many quite remote from my usual areas of expertise.
16th November 2011 – If you ask a child to draw a physicist, they’ll usually draw you a disheveled man in a lab coat. But looking around the hundreds of physicists eating lunch at CERN today, I saw many women, only one or two that could be classified as disheveled, and zero lab coats. Yet this image persists.
16th November 2011 – The ATLAS Experiment presented its latest results at the Hadron Collider Physics Symposium 2011 in Paris, France (14-18 November). Many of the most recent searches and analyses are based on more than double the data available at the last big conference in August.
15th November 2011 – It’s not every day you get to explain ATLAS to a group of journalists with just a pop-up book as a prop. But, as some readers might already know, this is no ordinary pop-up book. ATLAS and the LHC leap from the page in incredible detail thanks to paper engineer Anton Radevsky’s wonderful designs. A new edition of the book has just been released in French, so at the end of last month I found myself travelling in to the centre of Paris from Orsay for the press launch.
1st November 2011 – The clock just turned 2:00 a.m., again, on LHC Page One – the machine’s online status viewer – and I’m pondering just how I ended up on the longest shift of the year. I normally love this evening, snuggling under a warm comforter for that extra hour of late-autumn sleep. But, this year, on the very hour we ‘fall back’, I am cuddling with the controls of ATLAS’s 46 meter long muon spectrometer, a bar of chocolate and an extra cup of coffee. So be it.
28th October 2011 – In an amazing year that has exceeded our expectations, the Large Hadron Collider has delivered, and ATLAS has recorded, over 5 inverse femtobarns (fb-1) of collisions. These units correspond to having 3.4 x 1014 or 340 000 000 000 000 total collisions. Most analyses presented at the last major conference (the Lepton Photon Symposium in August in Mumbai) made use of about 1 fb-1, so this is a big jump.
18th October 2011 – A new French edition of the ATLAS pop-up book, Voyage au Cœur de la Matière (Voyage to the Heart of Matter), will be officially launched from the exhibition Entrée en Matière at Paris' Trocadéro on Tuesday, October 25th.
11th October 2011 – The first time I drove to Fermilab as a grad student, I got kind of lost. However, once I remembered my adviser’s words of advice, it was suddenly easy to find the strangely shaped Wilson Hall, a.k.a. “the highrise sticking out of the Prairies”. During my PhD years with the CDF Collaboration, I went there many a time – to attend meetings, to take shifts. The Chicago area summers were harsh, and so were the winters. On early morning shifts over the Christmas week, I realized that all too well. CDF had over five hundred collaborators at that time and this was my first introduction to a big experiment. Despite its size, everyone still seemed to know each other and it was one big happy family.
3rd October 2011 – The Tevatron collider, the scientific predecessor of the LHC, was shut down last Friday after 26 years of operations. Situated at the Fermi National Accelerator Laboratory (Fermilab) outside of Chicago, Illinois, the Tevatron collided protons with antiprotons at a center-of-mass energy just shy of 2 TeV. While it still held the title of the world’s highest energy colliding beams, it was the intellectual home of hundreds of scientists and students working as part of the CDF and D0 collaborations.
