6. Double decker why The double decker:
Allows to have the underground infrastructure on the same side of he LHC tunnel both for Point 1 and Point 5
Reduce the depth of the pit (≈ -11 m)
Provide solution to bring much nearer RF equipment to the RF crab cavities and to access the DFM from a convenient angle wit the SC link
Reduces the disruption in LS3 of the LHC tunnel
Provide the solution for the connection to the BBLR equipment if it will be integrated in the baseline (already accounted for)
Increase the distance between the LHC machine and the UR/US providing further vibration reduction and good radiation shielding
It considered that the following equipment can be installed in the LHC tunnel
Q.H. power units: possible location present installation area for the IT power converters
Extra collimation racks near the present collimation racks

7. Double decker safety
All required ventilation and safety ducts have been added as such for this integration. The real related loads should be re-analysed in the next optimisation phase
Emergency rooms have been installed along the tunnel length
Present solution do not feature the propose safety exit in the proximity of UA53. The implementation is an issue of civil engineering and in depth analysis of the impact in linking the LHC tunnel and the double decker structure (importing risks?) is udner completion. Its adding it is transparent from the integration point of view a part from ventilation and accesses. More information are necessary to complete the study and it will be an option in the CE MS

43. From now to the model for design contract signature
Revise shaft dimension: can we reduce in diameter now that we have the full view?
UR:
Warm cables and related cooling requirements
Implement cooling reduction capacity after the Q4 and cable length reduction that we did in 2nd half of august
The integration lay-out has changed-> reassess the warm cable length-> possible further reduction in cooling-> reduction in the electrical request
Magnet powering
Dumps and switch suppression-> reduction of volumes
Revise of the whole circuit: ramp down time issue and magnet current reduction
Corrector current: 1st step check current for the loss computation and then check possible reduction RF
After removing the dump the Faraday cage will be the element determining the tunnel section-> section reduction if possible till align with the needs in other section
RF:
Reduction of number of coax
Possibility to bring the supply of tetrodes to the surface. No analysis performed possible advantages:
Reduction of UA diameters
Reduction of cooling needed in the UA-> reduction of the electrical demands underground
Assessment of the real needs and efficiency for the smoke extraction-> CV needs reduction-> EL reduction
