After H1 lost lock this morning, the vacuum team started some work on HAM1, which gave me an opportunity to do a much-needed adjustment of the FSS RefCav alignment. As I expected, this was a very straightforward alignment where I was able to get immediate and significant improvements by walking the beam into the RefCav mostly in pitch, but some in yaw also (all with the IMC offline). My results:

• TPD start: 705 mV
• TPD end: 830 mV

A great improvement; even better than the alignment was before the drop-off over the weekend.
