First ATLAS muon chamber arrives from Greek production line
Greek delegate to CERN Council, Professor Emmanuel Floratos
(front, centre), accompanied by members of the Greek team, with
the first ATLAS muon chamber built in Greece installed in the
x-ray tomograph at CERN.
…the first precision chamber to come off a production line was built by a collaboration of three Greekuniversities and it arrived at CERN from Thessaloniki on 5 August. This chamber is the first complete model of 1200 that will be built around the world over the next few years.….
Verifying the alignment of interferometer beam optics on the ATLAS
experiment's X-ray tomograph at CERN. A small muon chamber from
Greece, destined for the barrel region of the detector, is on the tomograph.
It went on to pass the test with its wires showing an average fluctuation
of just 13 mm from their nominal positions. To pass the test, a chamber
has to score less than 20 mm.
