The new LHC accelerator will have two big detectors of the same kind as DELPHI in LEP (+ two specialised detectors). These two are named ATLAS and LHC.
The construction of the ATLAS detector is similar to that of the DELPHI detector, but ATLAS is much bigger. When it has been completely assembled ATLAS will be about 22 meters high and 44 meters long.
Click the link below to start an animation that shows the ATLAS detector seen from the side. Inside the animation you can click on the different detector parts or zoom into the inner parts of the detector. The animation needs Macromedia Flash Player.
