1. Wednesday Ramp single nominal bunches for loss maps
Ramp OK, losses in squeeze (orbit feedback forgotten)
Roman pots in to 25 sigma (V) and 30 sigma (H)
Loss maps performed with remaining beam (~ )
Ramp down and access for ALICE “in the shadow”
Quench power supply in 45 failed – needed access
Beam again ~ 18.00
Physics fill with 13b using multi bunch injection
Injection not as clean as after setting up on Tuesday
Stable beams from around 22.30
“It was again tedious to find ALICE”
Physics all night

9. Interventions needed
BLM crate exchange IR7 (to be done before 24b physics)
4-5 hours (including system tests).
Recycle of undulators in IR4 needed before Friday 30th
3 hours no beam
Magnetic probes in the machine for the studies related to the hump - access would be required in point 5 (GA, LW)
2 hours in the shadow
