Today, we installed the Pcal in-vacuum periscope structure at Xend.

Everything went smoothly (see photos)- uncrate, crane from East to West side, set on Installation Entry Pad, slide into adapter on "teflon highway."

We left the structure sitting inside the adapter (it is very stable in this configuration and cannot tip over due to mechanical interference).

Tomorrow, we plan to start work early in hopes of finishing up tomorrow, leaving the structure in its staging position awaiting the Cryopump/Manifold baffle installation.

Properly-fitting flange protectors were picked up from the machine shop today.  We will install them as soon as they are ready, hopefully tomorrow.
