Open topics – Phase 1 § Meeting with the survey team was on Wednesday 01/07/2020: § Alignment system was inspected § From our understanding the system works good § Waiting for the report logo area I. Papazoglou – G. Schneider, WP 13, BE-BI-ML 14
Last open topics – Phase 1 & 2 § Cabling: § § Powering pumps: § § VIC Done and approved. No civil engineering work necessary to open the hole but only to close it Check clashing with the gas injection chamber support: § § It is done Gas line: § § All cables in place BGI cabling: § § BGC main camera cables Fibre rack in installation process, by Stefano Mazzoni. BGC secondary camera cables For BGC phase 2 but afore mentioned rack has enough capacity for this as well. Laser power cable For BGC phase 2 but capacity is in place. For BGC phase 2, support currently in preliminary design. Cabling integration: § Started doing this. We are finalizing the pressure sensors to be used before doing the cabling for them. Cabling for valves and TMP are added. logo area I. Papazoglou – G. Schneider, WP 13, BE-BI-ML 15
