3. October 20th, 2005Mar3 Agreement Cables and connectors* between SG - US - UX - SG are procured and installed by the experiments to PH-DT1/Gas specification After several iterations, the cable schedule for the 4 experiments are released, available in EDMS The Gas Group takes full care of cables between racks in SG and US * In ATLAS, the Gas Group will assemble the connectors (after cable installation) S. Pavis
