2L02
After extensive troubleshooting in 2L02 to resolve the issue of the zone not going into IDLE. We discovered that we have a bad 3402 cable going from the CAMAC to the cross connect. The cable issue will be fixed on Monday so the zone can get certified by PSS and at first opportunity troubleshoot the initial AIB issues with 2L02.

Dissolved oxygen sensors measuring West ARC, South LINAC, and East ARC are not functional and has not been able to be repaired. Replacement sensors installed read accurately for a day or so and then the reading drifts up. Dissolved oxygen levels have been measured with a portable sensor to verify de-oxygenation equipment is functioning properly. The existing dissolved oxygen sensor manufacturer has stated the dissolved oxygen sensors are being discontinued.

The subcontractor successfully completed testing of the revised chiller plant control system programming. Communication failures were simulated at both remote chilled water sensors and there were no rapid changes in secondary pump speed control nor significant increased secondary chilled water supply pressure. The system responded as expected maintaining stable system chilled water supply pressure and chiller plant equipment operation. Final commissioning is scheduled to begin Monday morning.

Recorded 0L02 and 0L03 BPM spectra using the BPMSEE waveforms from EPICS for an hour to see if there's a correlation with the 0L02 BCM temperature cycle. The heater should be causing 60 Hz beam motion. Beam current to FC2 was 15 uA from A laser.
Within the resolution of this measurement, there's nothing there. I will try a few more things later (e.g., show lowpass-filtered time-domain data or RMS thereof vs time slice) but am not expecting a conclusive result.
Much better frequency resolution (though not necessarily lower noise floor) may be obtained with Tom's DAQ.
