5. Interventions on Point 4
No empty of RF cryogenics
No access in RUX 45 during the TS2 (RF cavities filled)
Access in RB44 and RB46 from Monday to Wednesday 14h00 (BI activities)
Presently a VIC is foreseen in UX45 on Tuesday, to anticipate the PR refurbishment foreseen during the YETS
Last Tuesday (29th Aug.), during the LHC coordination meeting  request from Gino Cipolla to access in RUX 45 to replace some dampers. This request is presently not compatible with the decision to not empty the RF, due to the Helium Spill risk.
TE-EPC would like to test and power on the power converter RA47U3, but this is under discussion, because this should prevent any access in RB44 and RB46 (tbc)

TDE U62 Investigation
Activities declared:
Opening of the shielding
Visual inspection
Robotic intervention for leak detection
Possible leak rate reduction (if any)
Closing of the shielding
Due to RP restrictions the shielding cannot be opened before Tuesday morning (TBC by RP)
Material can nevertheless be transported in the area already on Monday after RP patrol
Open points:
Cryo conditions for the passage of the equipment above the QRL ?
Installation of N2 lines ? VIC to be planned?
Are they some investigations planned in UD68?
