Procedure of drift tube wiring
The incoming industrially produced components for tube wiring is:
- Thin wall precision Al – tubes;
- Gold plated 50 µ tungsten-rhenium wire;
- End-plug (which consist from end-plug body with high precision reference surface, wire holder for precise wire positioning, O-rings)
But as far as the performance of MDT muon system is determined by the performance of drift tubes and moreover there is no possibility to replace/repair single detector from the muon chamber the process of tube wiring and set of the tests must be relevant (QA/QC – procedure !!).
