Facing new safety-challenges in a large particle accelerator experiment at CERN

Particle accelerators and the detectors for the observation of beam- collisions are becoming larger and/or more powerful, as well as more international as to resources in financing and sharing in research. The Compact Muon Solenoid (CMS) at the European Laboratory for Particle Physics (CERN) in Geneva is such a modern instrument. The Compact Muon Solenoid (CMS) is one of the two new large detectors which will be installed as part of the Large Hadron Collider (LHC) at the European Laboratory for Particle Physics (CERN) in Geneva, Switzerland. The LHC will be the worlds most powerful experimental facility of this type, for planned operation by the year 2005. The machine, mainly to be operated as a proton-proton collider will produce fluencies (luminosities in accelerator language) of 10 E+34 /cm2.sec, beam energies of 7 TeV and will use magnetic fields of up to 8.3 T in the bending magnets and around 4 T in the spectrometric magnets of the large detectors.
