More collisions at 2.36 TeV

14th December 2009 – This early morning Dec.14 at 2.40, after a 8 minutes ramp, the energy of the two LHC beams has been brought up to 1.18 TeV again.

Thorsten Wengler

14th December 2009 – Thorsten Wengler can still remember exactly where he was when the Berlin wall fell in November 1989: on night guard, sitting atop a pile of arms and ammunition in the woods outside of Potsdam, Germany, alongside three of his fellow East German soldiers. Well, in truth the other three were asleep, and Thorsten – a trained radio operator – was tinkering with a radio that was intended only for East German radio stations, trying to pick up his favourite West Berlin channel – the one with the best music.

ATLAS increases its active channel count by one order of magnitude

10th December 2009 – On Sunday December 6, 2009 at 8.00 the ATLAS Pixel Detector has measured, for the first time, tracks emerging from LHC collisions. It has been a very smooth start.

First collisions with the pixel detector

7th December 2009 – It's been a busy weekend for ATLAS. Last night, well, actually early this morning, we received the "stable beam" flag from the LHC.

First collisions in ATLAS

23rd November 2009 – A few days ago, loud cheers and happy faces filled the ATLAS Control Room while the whole detector lit up: protons are back at the experiment's door, and everybody forgot in a second the long year of waiting for the Large Hadron Collider (LHC) to resume operation.

LHC beams and events back in ATLAS

21st November 2009 – Loud cheers and happy faces fill the ATLAS Control Room while the whole detector lights up: protons are back today at the experiment's door, and everybody forgets in a second the long year of waiting for the Large Hadron Collider (LHC) to resume operation.

Hans Peter Beck

2nd November 2009 – Unlike most of us at CERN, Hans Peter Beck is a Swiss native. He grew up in places like Weggis, on the shore of Lake Lucerne; Wolfenschiessen, in the mountainous interior of Switzerland; Dietikon, a suburb of Zürich, and finally in Zürich itself. He completed his matura – the Swiss secondary education – at the Mathematical Natural Science Gymnasium, Rämibühl, Zürich. Although he received better marks in chemistry at the time, physics held a much stronger attraction because it delves into matter at its most basic.
