The in-vacuum periscope structure for Yend was pre-aligned in the H2 Laser Area Enclosure.  Mirror mounts were removed and it was wrapped and transported to EndY where it was installed inside the A7 adapter.  It was moved to the staging location where it was rotated 90 deg. to allow access for the Manifold/Cryobaffle installation work.

Tools and installation tooling were left inside the periscope frame in anticipation of its move to the final location after the baffle installation.
