ATLAS particle detector
ATLAS is one of five large particle detectors associated with the Large
Hadron Collider at the CERN laboratory
near Geneva. "ATLAS" stands for "A Toroidal
LHC ApparatuS. It is
an enormous general-purpose detector – 45 meters long, 25 meters in
diameter (as tall as a five-storey building), and about 7,000 tons in mass.
ATLAS took ten years to plan and a further ten years to build. Construction
of it was completed in early 2006. It will begin gathering data when the
Large Hadron Collider is turned on in 2007. About 1,800 physicists (including
400 students) from more than 150 universities and laboratories in 35 countries
are involved with the ATLAS experiment.
- About 3,000 km of cable are used in ATLAS
- Although heavy, ATLAS has enough enclosed empty space that it
would float in water
ATLAS has many different systems for detecting a wide variety of subatomic
particles that will be produced by the extremely high-energy collisions
taking place in the Large Hadron Collider. Among the particles that it is
hoped it may detect is the Higgs boson,
an entity predicted to exist by the Standard
Model of particle physics.

Did the infamous Borg steal ATLAS technology?
Or have CERN scientists been watching too much Star Trek? Should we be told?
