Roger Jones, a physicist who I interviewed for the “”http://www.nature.com/news/2008/080910/full/news.2008.1095.html">Voices from the collider" segment, has posted some first images from ATLAS on his blog. Like CMS, these images, were taken when the beam struck a collimator, so they’re not from actual collisions. I actually just took a stroll to the ATLAS control room, which is a hop and a skip from where I’m sitting now, and it was full of energy.
Roger explained to me that this was the first taste of real data for the ATLAS subsystems, and they were frantically trying to understand what the detector was showing them. The mood was a little tense actually. Nothing like shaking down a brand new, multi-billion-dollar detector to make everyone jumpy.
