Trim rack lost communication with trim cards, DC Power investigated and found an issue with channel 13 MBC4S03V. They replaced it and it took setpoint and cycled.

For "old style" tuning we need manual betatron match quads in the spreaders. I pulled ced2elegant decks for the spreaders and started looking at outputs to suggest candidates for tuning knobs to the optics team. Avoiding using quads in the spreaders themselves so we can avoid leaking vertical dispersion into the arcs.

For 4E we can use MQL4E02/MQA4A01 horizontal and MQL4E03/MQA4A02 vertical.
For 5E we can use MQL5E02/MQL5A01 horizontal and MQL4E01/MQL4E03 vertical.
For 6E we can use MQL6E02/MQL6A01 horizontal and MQL6E01/MQL6E03 vertical.

We've done all of the dispersion corrections up to 4L and done a 3R Y Beta that showed some improvement in the vertical differential kicks using MQA3R07 and bringing it 8% weaker. It was in a positive direction so we might try to bring it even weaker and check the 4E harp + fopt. Currently we're blocked by SL27B19 being down.

Yesterday we used the dynamic signal analyzer to evaluate the output of ARC1 through ARCA for low‑frequency components. No harmonic content was observed on any supply. A minor 60 Hz peak at –67 dBV was detected on ARCA, and a 120 Hz peak at –70 dBV was observed on ARC6 and ARC7. ARC1 and ARC3 showed no measurable harmonic peaks (see attached screenshots).
The 60 Hz and 120 Hz components are consistent with normal power‑line and rectifier ripple coupling. Their amplitudes are extremely low and are not expected to have any operational impact.
