Installation of the first of the big wheels of the ATLAS muon spectrometer, a thin gap chamber (TGC) wheel. The muon spectrometer will include four big moving wheels at each end, each measuring 25 metres in diameter. Of the eight wheels in total, six will be composed of thin gap chambers for the muon trigger system and the other two will consist of monitored drift tubes (MDTs) to measure the position of the muons.

This huge wheel contains many muon chambers. They will be used to measure the paths and energies of muons, highly penetrating particles that pass through the inner regions of the detector. A wheel will be mounted at either end of the detector to observe the path of muons as they leave the detector. October 2006 Photo #: 0610010_01 |
