After further troubleshooting the calibration of the analog read backs for the voltage and current of zone 1L15 was completed. Also the calibration of both the digital and analog voltage and current read backs for zone 1L16 were completed. Further troubleshooting required for calibration of the current overload circuit.

This work was to be scheduled to be done concurrent with the same work being done at the North Access building. I have changed this date to February 1 and 2.

We have been postponing this work to avoid the possibility of disrupting the ESR; now that they will be shutting down the ESR for several days I would like to take advantage and schedule the North Access outages to coincide with the ESR outage. I have entered this for February 3 and 4.

I suspect the problem seen in the linked entry would be corrected if XSOF were set to -2.225 as before 2016. Present value is zero, figure 2. YSOF has been constant for a decade, figure 3.

Investigation of low frequency AM instabilities in cav1 and cav2 field:
Found measurable cross-talk between RF testing cables (Super Flexible SLC) . Because we are measuring AM modulations in the range of 0.05% , cross-talk level was enough to corrupt the results.
Cables have been replaced and cavity filed stability measurements show very good results:
AM modulation < 0.03 % RMS
Integrated phase noise < 270 fsec ( integrated between 1Hz-3 MHz)
most prominent mechanical modes at 3.6 Hz, 11 Hz, 22 Hz

Simon Wood, Jason Delk and I tested (2) more upgraded
Utility Chassis in the UITF trim rack IT07.

The first chassis would turn on and ramp to 25V then trip
off; it happen twice, so Simon and I try the second chassis
and it worked OK. We ran the chassis through all stages of
the test procedure and it pass all stages.

So Jason and I reinstalled the first chassis again, and this
time both bulk power supplies ramp up to 30V.
We ran the chassis through all stages of the test procedure
and it pass all of the stages.

The (2) chassis where place in the machine at E101B11
and E201B11
