4. Location of the TANB installation in L8
The TANB will be installed between D2 and the TCTPH and in consequence, the BPMs will be displaced next to the Y-chamber. D2

6. Present situation
During the visit on 24/03/2019, it was noticed that there might not be enough space for the BPMs drilling plate integration.

10. Proposal for the new position of the electrical boxes [I]
Displace the electrical boxes about 2.5m away toward the IP8.

11. Proposal for the new position
of the electrical boxes – integration model
Any inconvenient from the plugs users?

15. Conclusions
Displacement of the electrical boxes is required for the BPMs drilling template integration.
Proposal: displace them about 2.5m towards IP8 where there is clear space.
Preliminary cost estimation: ≈500CHF.

19. Site visit on 12/03/2019 Left side of point 8.
ACTION: coffret on left side to be installed together with the other two coffrets on the right side in a common new support. Connected cables can be shifted towards the IP to clear the space (cables position have to be 5cm away from the Y-chamber support for space allowance in case of vacuum support removal).
