Entrance B to the CERN complex	Typical small offices beside the street	Lots of transformers (foreground) and liquid helium hoppers (background) everywhere
The main computing center	Construction of the magnets for the ATLAS experiment	Finished magnet on the test bed
ATLAS detector schematic - the whole detectors is 46m long and 25m high		Three photos below: Construction of the inner detector (red part) The magnets (photos above) are attached around the inner detector to form a cylindrical field. You can see one of the large magnets in the schematic - it is the grey ladder-like item in front of the red calorimeter, just above the yellow supports. More information: ATLAS detector and LHC (Large Hadron Collider)
Muon chamber module for ATLAS	Description of the muon drift chamber	All the blue modules in the ATLAS schematic are such muon drift chambers The single alu-pipe detectors operate at 3080V; gas mixture: 3bar Ar:CO2 (97:3) Such chambers contain a wire of typical 50um In the photo of the detector module on the left, every "knob" on the front side is one connector to one drift chamber pipe!
The Accelerator Factory
Construction of the superconducting quadrupole magnets that will be used for focusing protons before they are injected into the LHC
The Anti-Matter Hall - How it works: AM Factory @ cern.ch
Anti-protons - produced by the accelerator - are collected in the outer ring (shielded with concrete plates), decelerated and collected in the area inside the ring	Red quadrupole magnet used for focusing the anti-protons. Another similar type is used for keeping the anti-proton beam in the middle of the tube.	Status screen of the decelerator: The linear falling lines represent slow-down intervals, while the flat parts are the beam focusing intervals. It takes 84 seconds to slow down the beam, until it is ready for collection
ATHENA Anti-hydrogen production area	Another view of the ATHENA area More info on ATHENA
Technical Control Room: 24/365	Funny traffic sign in CERN: Don't drive here if your vehicle weights over 30t. Otherwise your roof will explode!
