Everything looks alright except for one slightly worrying trend.  On the Weekly Chiller attachment, the diode and crystal chillers (H1:PSL-OSC_XCHILFLOW and H1:PSL-OSC_DCHILFLOW) both see a slow loss in flow, as does the FE water circuit (H1:PSL-OSC_AMPFLOW) and the HPO power meter water circuit (H1:PSL-OSC_PWRMETERFLOW).  In addition, the flow meter for the laser head 1 water circuit (H1:PSL-OSC_HEAD1FLOW) is also showing a slow drop in flow rate.  As there is no coinciding increase in humidity (found on the Weekly Env attachment) I don't think we have a water leak.  Also, it looks like the Diode chiller flow has leveled off, while the crystal chiller flow does not appear to be doing so.  Combine this with the slow increase seen in the pressure of the crystal chiller water circuit (H1:PSL-OSC_PRESS1 and H1:PSL-OSC_PRESS2, sensors located respectively at the entrance and exit of the HPO water manifold underneath the PSL table), this may be an early indication of a flow issue (for example a small obstruction restricting but not blocking the flow) in the crystal chiller water circuit.  There's no way to know for sure right now, but this is something we are going to keep a very close eye on.
