ENGAC TeamThe four main LHC experimentsAcceleratorsCERN-AC-9906026This diagram shows the locations of the four main experiments (ALICE, ATLAS, CMS and LHCb) that will take place at the LHC. Located between 50 m and 150 m underground, huge caverns have been excavated to house the giant detectors. The SPS, the final link in the pre-acceleration chain, and its connection tunnels to the LHC are also shown.1999http://cds.cern.ch/record/40525http://cds.cern.ch/record/40525oai:cds.cern.ch:40525 L3: Decay of Z0 to muon-antimuon pairExperiments and TracksCERN-EX-9106038This track is an example of real data collected from the L3 detector on the Large Electron-Positron (LEP) collider at CERN, which ran between 1989 and 2000. A Z0 is produced in the electron-positron pair collision and quickly decays into a muon-antimuon pair. The muons pass through the entire detector without being absorbed.1991http://cds.cern.ch/record/629157http://cds.cern.ch/record/629157oai:cds.cern.ch:629157 CMS: Simulated Higgs to two jets and two electronsExperiments and TracksCERN-EX-9710002This track is an example of simulated data modelled for the CMS detector on the Large Hadron Collider (LHC) at CERN, which will begin taking data in 2008. Here a Higgs boson is produced which decays into two jets of hadrons and two electrons. The lines represent the possible paths of particles produced by the proton-proton collision in the detector while the energy these particles deposit is shown in blue.1997http://cds.cern.ch/record/628469http://cds.cern.ch/record/628469oai:cds.cern.ch:628469 A spray of particlesExperiments and TracksCERN-EX-8211511These tracks are produced by high energy particles that have been created in the collision of a proton and an antiproton in the SPS collider at CERN. Particle detectors use electronics and complicated devices to recreate the tracks left by real particles. Such detectors are usually embedded in a strong magnetic field, causing the charged particles to follow a curved path so that they can be identified and measurements can be made of their momentum.1982http://cds.cern.ch/record/39454http://cds.cern.ch/record/39454oai:cds.cern.ch:39454 ENGTaylor, LucasCMS: Higgs boson decays to four muonsExperiments and TracksCERN-EX-9710002This track is an example of simulated data modelled for the CMS detector on the Large Hadron Collider (LHC) at CERN, which will begin taking data in 2008. The Higgs boson is produced in the collision of two protons at 14 TeV and quickly decays into four muons, a type of heavy electron which is not absorbed by the detector. The tracks of the other products of the collision are shown by lines and the energy deposited in the detector is shown in blue.

Silicon wafers detect the position of passing particles with great precision, allowing the tracks of the thousands of particles emerging from collisions to be accurately reconstructed.1997-09-02http://cds.cern.ch/record/39442http://cds.cern.ch/record/39442oai:cds.cern.ch:39442 Maximilien BriceCERN openlab for Data Grid applicationsExperiments and TracksCERN-EX-0306019<HTML>Pictures taken for the CERN Openlab annual report Picture 01 : Sverre Jarp, chief technology officer of the CERN openlab, with equipment from Enterasys Networks Picture 03 : One of the nodes in the high-performance CERN opencluster.

The Data Grid looks to revolutionise the way large amounts of data are processed by allowing computer centres around the world share processing power. Developments such as this are vital to handle the huge amounts of data produced by the new LHC accelerator that will start up at CERN in 2008.2001-02-13http://cds.cern.ch/record/42115http://cds.cern.ch/record/42115oai:cds.cern.ch:42115 Maximilien BriceRainer Tobbicke of CERN with the 28 terabyte storage system sponsored by IBMIndustry and TechnologyCERN-IT-03060372003-06-17http://cds.cern.ch/record/624198http://cds.cern.ch/record/624198oai:cds.cern.ch:624198
