We have flushed, rinsed and flow checked JA dipoles @23,28,30 and 32. All flows are in expected values. LCW water was in good order today.

The team did a great job, thanks to all.

DC power and RAD notified.

We continue to flush the arc 5 & 9 dipoles as needed/when they fail on OT and the FLIR pictures indicate the other dipoles in the string that look like they nearing a failure condition. However, we don't have any FLIR pictures from the North side of the arc of the arc 9 dipoles. The current arc 9 dipole failures is similar to the initial arc 5 failures. We don't know how long to expect arc 9 to hold up before we have another OT trip.

During next maintenance opportunity, MQK8A11 (W301B08 ch. 10) should have it's output cable connections checked. This would be upstairs work in the service building like the others that have been checked so far.

Using our attender card I took measurements of magnet MBC8A01H Ch. 15 and it was reading 1.8 ohm and +/- 32V which it should be reading.
I then took measurements at magnet MBC8A01V Ch.16 and it's reading the same as MBC8A01H.

I place the original red tag trim card from the MCC back into Ch.15 slot and it worked properly.

Fixed at zero with 50-70 uA CW through the line to Hall C except for occasional blips. This is the BPM between MZAAS04 and MXXAS05. IIXAS01A, which is mounted just after MXXAS05, reads 24 kR/hr with 80 uA to C. It would be helpful in steering in the area if this BPM was functional. This can wait until the SAM. IPMAS00 works, figure 4.

I haven't checked the other BPMs in the S01 stack.
