PSL 10-Day (+7) Trends

FAMIS 31119

Pulling these trends for an additional week back to capture the duration of the holiday break. Main changes over this time were the PMC and RefCav transmission dropping while PMC reflected power increased, but not sure exactly why at this point. The periodic temperature spiking we've been seeing in the diode and chiller rooms appears to have mostly stopped as of the start of the break. We think this was due to the mini-split turning on, so I'll check with facilities if a setting was changed that could have caused this.

There has been work in the enclosure starting as of yesterday, which explains the change in many trends starting then.
