[dsg-hallb_rich] RICH spherical mirrors delivered

[Tyler Lemon]

Hello,

Shortly after my last email, the mirrors were moved to the EEL 121 DSG small cleanroom and unpacked.

Both mirrors were opened for inspection and then stored in the cleanroom inside the closed-cell foam padding that was inside each mirror's cardboard box (cardboard is not allowed in cleanroom).

Attached are photos of each mirror and how each mirror was left in the cleanroom. The mirrors are sitting inside the foam with its curvature pointing towards the table (this is how they were packing during shipping).

We'll start the d0 tests tomorrow.

-Tyler

Hello,



As noted by previous emails, the two RICH spherical mirrors have been delivered to JLab.



I am at the lab and will move them to the cleanroom as soon as Shipping & Receiving finishes processing them.



We will plan to start d0 tests tomorrow morning.
