*[Refining optics corrections at top energy]: Local chroma at injection wihtout QFB (last point with QFB). ADT-ACD settup in optics mode at injection, 10mm kicks. ADT-ACD at FT, large enough kick to measure linear optics. At FT had problem with BPM concentrator for B1. Local chroma of B2 at 18cm. Kmod at 160 and 120 urad for effect of crossing-scheme on lumi imbalance. Kmod at 120urad with Felix waist knob. Kmod and ACD with 28april waist knob. ACDkicks and xing scan for b6 feed-down to f0140 RDT.

*[Pb Ion Optics Part 3]: Attempted to validate Pb optics with enf of squeeze corrections from last time, as filler during validation of loss maps during vaccuum issue. Quick measurement at injection to check BPMs, but then OP were unable to get cycle to ramp due to inconsistency in ADT settings. Gave up after several hours as LHC switching back to lumi production. Includes summary of previous ion fill results.

*[LRBB Beta-beat compensation with flat-optics]: Tried for the first time to take measurements of the LRBB-optics in both beam-1 and beam-2, using 2 separate fills. No issues encountered when switching the role of weak/strong beams between beam1/2. In Beam1 there was no visible effect on the lifetime. In beam2 however the lifetime appeared to degrade slightly as the MO were removed.

*[New IR7 optics, squeeze validation]: Checked the new IR7 optics along the squeeze down to 60cm/18cm, including new corrections scaled from nominal cycle. Beta-beating and normalised dispersion good at all points in the squeeze. Vertical dispersion bump observed in IR7, getting stronger as the squeeze progresses (up to Dy=1m). No issue for the second fill of MD with lossmaps but should be corrected for operational use. The sdisp knob is to be included in model. Kmodulation at 18cm shows similar results to nominal ion cycle.
