Description: Record of the experimental data in real time. Оn the picture - a momentary recording.

Continuously recorded and processed using a super powerful computer systems, huge amount of information obtained by the detectors ATLAS collaboration. A special filtering information to be given only significantly important for shaping the experimental physical findings. In each second, the monitoring teams can learn if it there realized a new discovery event and what is the information from the physical point of view, associated with it.

The Trigger and the Event Filter (when any of the protons collide) then select for permanent storage only about 200 "interesting" events per second. If all data would be recorded, this would fill 100 000 CDs per second. This data rate is also equivalent to making 50 billion telephone calls at the same time.

Computing: There are more than 5 million lines of code written for event analysis. The computing effort uses 3 000 online PCs and 100 000 PCs for offline processing and analysis.

Data Recorded per year: The 3 200 terabytes of data that will be seen each year are the equivalent of the content in: 7 km (4 miles) of CDROMs stacked on top of each other, 600 years of listening to songs, 3 billion books.

Source of information: Official information materials and publications of CERN.
