The main work for installing the optics and the light source for a Y-end OpLev has been finished.
The beam is roughly aligned and the optics as well as the QPDs adjusted to their dedicated position.
However, cableing hasn't been done yet, and thus, a fine adjustment especially of the LS OpLev QPD is still missing.
These things may be done in August as long the dummy mass is used for performing the cooling test.
PR3:
During the replacement of the viewports in the PR3 chamber, Akutsu-san and I shut off the OpLev light source.
During my next stay, I will readjust the OpLevs.
