The wire positions in the DT chambers have been measured during construction, and the chambers are treated as ... On each chamber, LED light sources are monitored on mechanical reference structures called a#39;Module for Alignment of Barrela#39; (MAB). ... z distance of the MABs is monitored by cameras on the MABs monitoring light sources on carbon-fibre a#39;Z-barsa#39;. ... Transfer to the CSC coordinates is made in the disk plane at constant z, where three laser beams connect two SLMs atanbsp;...
