The FSS TPD has been slowly trending down again, so I did a quick remote adjustment of beam alignment into both the PMC and FSS RefCav today.
Starting with the PMC, I turned the ISS OFF, then adjusted the beam alignment from the Control Room using our picomotor mirrors. Unfortunately, I did not get any improvement in either PMC Trans or PMC Refl. PMC Refl has been very slowly increasing over the last couple of months, it may be time to take a look at adjusting the amplifier pump currents; we'll monitor this over the next week or two and move forward from there as necessary. To end the PMC adjustments, I turned the ISS back ON. It was diffracting ~4.2% (jumping between 4% and 4.5%), so I decreased the ISS RefSignal -1.99 V (from -1.98 V) to lower this a small bit. The ISS diffracted power is now hanging around 3.8% (jumping between 3.6% and 4%); at this new diffracted power, PMC Trans is ~105.7 W.
Moving on to the FSS RefCav, with the IMC unlocked the TPD began at ~0.78 V. I was able to get the TPD up to ~0.809 V, an OK improvement but not back where it was at the end of the last on-table alignment. With the IMC locked the TPD is ~0.813 V.
