[Shane, Jon]
Today's CyMAC work:
Finished assembling external power supply cable for the timing
chassis (see attached image)
Also did some debugging of AA and AI chassis re: power issues. After testing voltages at various test points
on the power regulator board (TP1-TP6) in the AA chassis, it seems like it's the source of the problem. Used bench DC power supply to test, running 15V, |

Concluded assembly of timing chassis for CyMAC today; see attachment 1 for interior set up of chassis. Installed front and rear panels, wired on/off switch
and LED assembly, and tested to confirm everything is powering on correctly. Also tested the outputted timing reference that will go to DAC and ADC adapter
boards (see attachment 2 for output 1 and attachment 3 for output 2). |

Here are the counts from the clean room floor today. The counts should be dated- the ones from today (2/23/23) are the last 8 in the chart. The first set
of 2 measurements from today were under the table by the clean room entrance, the next two were under the table by the vacuum chamber, the next two were
on the floor by the vacuum chamber lid, and the last two were on top of the table for comparison. All measurements were taken using 2 minute sample time. |

The occupied clean room measurements were unusual in that they generally got larger towards minute 6 instead of settling and going to zero, and for this
reason didn't stay beneath the class 5 requirement at the end of the samples. The unoccupied counts look more similar to what was expected, and generally |

being stored in bags/bins on the upper shelf of the desk aren't clean?) but will focus cleaning efforts on this zone next time. |

Summary of the issue we've been having with the timing chassis: when we connect only the Valon 5015 to power, the timing signal comes
out of it sinusoidal as expected and the status lights are steady and all looks good. As soon as we connect the 3010 to power, the signal (both coming
out of the 5015 and coming out of the 3010) go flat and the status lights of the 5015 start to flicker.

|
[Ma, Luis, Shane]
Working theory for the timing chassis issues had been that the 1A breaker was tripping and
causing the failure of the Valon 5015 and 3010 to output the timing signal correctly. We just tried bypassing the breaker, running 6 V on the benchtop
power supply (set the current limit to 1.5A), with the 5010 generating the sine wave to pass to the 3010. All worked correctly, and there were no issues. |

[Ma, Shane]
We replaced the 1A breaker in the timing chassis today with a 4A one, and tested that all is working
well. The chassis successfully outputted the correct signal (image attached). The real time models have also been restarted and the CyMAC diagnostics screen
is showing all green flags. Timing chassis has been closed up and reinstalled in the server rack. |
