Comb-lines for assembly of MDT-chambers for ATLAS experiment

A description of the manufacturing technique of comb-lines for drift tubes gluing during the assembly of MDT (Muon Drift Tubes)-chambers for the ATLAS experiment is presented. Under the requirements of the quality control, tolerances of the coordinates of signal wires in assembled chambers should not exceed 20 micron. The comb-lines for the tubes fixation that were made satisfy these requirements. The gluing procedure of the combs is described, results of control measurements during the comb manufacturing are given, and also the diagram of the distribution of the signal wire coordinates in the assembled chamber 'Module-0' is shown.
