I'm in the process of aligning the mode cleaner/ input beam.
I turned off the WFS and cleared their histories, adjusted the input periscope and re-aligned the mode-cleaner accordingly.
I then unlocked the cavity and centred the beams on the WFS.
MC transmission is ~3.3 and the REFL beam looks a little better.
However, turning the WFS on now lowers the transmission. More thought tomorrow.
I'm leaving the MC locked with WFS off. |
