Experts need an access to P8 service area (cryo zone in UX85). The repair will require opening the QURC and take ~3-4 hours. Afterwards, they expect at least 8h for the recovery. - During the filling, test with orbit bumps in P4 to check the effect on the BBQ tune measurements. With a -500um bump, a tune shift of 5e-3 was observed. The effect was much smaller for a positive bump. - At the start of the ramp, losses at TCLA.D6R7.B1 above 50\% of the dump threshold.
