Sleepless Nights Lead to First Results of 2010...
Do you hear that? The incessant typing? The coffee machines vending cup after cup? If you go to Building 40, or Building 32, Building 188, or to any one of the many graduate student offices around the world, you will hear the tap of key boards, the whir of disk drives, and even the occasional heated civil discussions with "elevated" voices.

Conversations on Shift
When the detector is running smoothly, neighbors in the ATLAS control room sometimes get conversational. A few days back I was on shift, quietly looking at plots on the monitor in front of me, trying to decide if one small sensor was misbehaving or not. “I have a question,” the shifter next to me said.

Its All About The Lumi!
Now that the LHC has established colliding stable beams at a center of mass energy of 7 TeV, the next step to maximize its physics reach is to provide the most luminosity possible. As Leo posted, we need to increase the number of proton - proton collisions to make sure we have a chance of seeing the physics that we are looking for. The reason for that is because different p.hysics processes have different probabilities. These probabilities are referred to as cross-sections (in a vague reference to the particle's size). If one multiplies a cross section by a luminosity than what you get is a number of events.

Life Imitating Reality
I was home sick today, probably from the stress of getting ready for "M-Day" (aka Media Day), more likely though I finally succumbed to the cold that had been spreading through the Control Room. As it so happened, my laptop had been in the shop because it experience an "incident" (actually I just dropped it) last Monday (the week before Media Day), and I just picked it up yesterday.

First 7 Tev collisions have been recorded in ATLAS
After ramping of the beams to 3.5 TeV and tuning, final checks, and some emotions due to an unforeseen beam dump, the 7 TeV collisions finally appeared on the on-line monitors of the ATLAS Control Room.
Big step forward in LHC operation last night
Last night a new very important milestone has been reached by the LHC: two counter-circulating proton beams have been accelerated for the first time to 3.5 TeV, the energy that they should routinely reach in the 2010-2011 running period.

A titan awakes
At approximately 2:40 am Central European Time, ATLAS saw particles from the LHC for the first time in 2010. As in previous LHC turn-on periods the first thing we see are beam splashes from the LHC beams as they slowly thread the beam through the LHC ring for the first time.

ATLAS increases its active channel count by one order of magnitude
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.
