Many more details to come, but Álvaro, Corey, and TJ installed the new H1 Optical Parametric Oscillator Suspension (OPOS) this morning (with Bubba as safety consult, and me as photographer.
I attach my the highlights of my pictures from the activity as direct images below. All pictures are collected, scaled down, and merged into a .pdf also attached.
Notes:
- During the install, we had to move
- the OMC TRANS path beam dump that was in the -X, -Y corner of the table (it was in the old position, and will need to be moved anyway)
- A ballast mass that was (unbolted and) shoved against AS WFS A. The table needs to be rebalanced anyway, so this it's a big deal.
- The second iris (closest to the OPOS and/or the future position of ZM1) capturing the beam path into HAM5. The location has been scribed in order to (hopefully) reproduce the position to high accuracy. See .pdf for detailed pictures of this. This will be re-installed omce we finalize the location of the OPOS and place ZM1.
- In order to successfully attach the installation lifting fixture to the OPOS, we had to remove a V-dump from one corner of the optical bench. This dump (and its near interference) is shown highlighted in the second picture (IMG_3648.jpg). This will be re-installed shortly.
J. Kissel for T. Shaffer The V-Dump mentioned above has been reinstalled.
Wonderful, congratulations!
Adding a few more pictures and a (late) update from yesterday.
Yesterday, Alvaro and I finished routing the cables and fibers that come from the suspension. The cables were attached to their brackets, but have not been connected to their cables that run to the feedthrough. The fiber feedthrough has not been installed yet, so the fibers are just coiled up and waiting for that. The AS WFS are not in the same spot as in the drawing, because of this we had to reroute some of the cables for these WFS (see attached).
Today we will unlock the suspension and rebalance, then when we are happy with that we will recenter the OSEMs. Sometime this week we will need to add the 2" mirrors, beam dump, ZM1, and hook up the rest of the cables.
