1. Integration – preliminary ideas on routing and tests
D. Calvo

2. 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

3. 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

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

5. 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

6. 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

7. 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

8. 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
