PSL Weekly FAMIS Tasks (FAMIS 3656 & 8428)

PSL weekly FAMIS tasks have been completed.

HPO Pump Diode Operating Current Adjustment

No adjustment was performed this week, as I could not get the laser power to increase by either operating current or temperature adjustments for the pump diodes.  This indicates a possible misalignment within the HPO resonator; any misalignment here is going to be extremely slight (a small misalignment can render the laser completely inoperable, so being down by ~1W in output power is a very small misalignment).  I have attached a screenshot of the main PSL Beckhoff screen for future reference.  This completes FAMIS 8428.

Power Watchdog Reset

I reset the PSL power watchdogs at 15:44 UTC (8:44 PDT).  This completes FAMIS 3656.
