Integration – preliminary ideas on routing and tests D. Calvo

Presented by B. Giraudo and D. Orecchini MVD integration – I step MVD assembled with the services inside the straw tracker and around the beam and target pipes in a dedicated laboratory at the GSI (? To be verified) [ about 12m x 10m] Routing from the GBT to the super modules done Routing from the DC/DC converters to the super modules and to the GBT done Routing of the cooling pipes from patch panels to super modules done MVD test performed using cooling system , power supplies and optical fibers with daq, locally Presented by B. Giraudo and D. Orecchini 2

Presented by B. Giraudo and D. Orecchini MVD installation – II step MVD – Straw tracker – Beam/Target cross system moves from the dedicated laboratory (?) to the platform in front of the magnet Presented by B. Giraudo and D. Orecchini 3

MVD installation – III step Connection of optical fibers, supply cables, cooling lines following the SCENARIO 1 SCENARIO 2 MVD test 4

MVD installation – SCENARIO 1 Supply cables from Racks to patch panels Optical fibers from Count. Room to patch panels Cooling lines from cooling plant + pressure controllers to be connected to the maniforlds around the beam pipe Intermidiate patch panels are installed in front of the magnet Issue with the optical fibers intermidiate connections ? Probably no Supply cables and cooling pipes are disconnected after the test for the sliding in the magnet of only the tracker More convenience in the test phase and in the installation because the supports are limited The voltage drop of the short cables from patchpanels to the DCDC is perfect All parts have to be arranged to avoid conflit with the phase of the calorimeter installation 5

MVD installation – SCENARIO 2 Supply cables from Racks (S2) Optical fibers from Count. Room (S2) Cooling lines from cooling plant + pressure controllers to be connected to the maniforlds around the beam pipe No interruption of the optical fibers and of the supply cables. No additional patch panels Long optical fibers and long supply cables (higher vol. drop) to handle with supports Calorimeter already in front of the tracker platform to fulfill the routing operation The calorimeter moves when the tracker slides inside the magnet Optical fiber and supply cables spares have to be routed from the beginning. All parts have to be arranged to avoid conflit with the phase of the calorimeter installation 6

MVD installation – IV step The system slides in the magnet Connection of the cooling lines Connection of fibers and supply cables at the patch panels in the SCENARIO 1 MVD test disconnection of the cooling lines and of fibers and supply cables at the patch panels in the SCENARIO 1 7

MVD installation – V step After the calorimeter installation Connection of the cooling lines Connection of the optical fibers and supply lines (SCENARIO 1) MVD test Supply cables from racks + patch panels in front of the magnet(S1) Supply cables from racks (S2) Optical fibers from c.r. + patch panels in front of the magnet(S1) Optical fibers from counting room (S2) Cooling lines from cooling plant connection + pressure controllers in front of the magnet 8
