[dsg-hallb_rich] RICH-II planar mirrors stored in DSG small cleanroom

[Tyler Lemon]

Hello Marco Mirazita,

For long term storage until they are installed in the detector, should the planar mirrors be stored horizontally (like the ones under the table) or vertically (like B2-R02 and B2-R03).

Subject: [dsg-hallb_rich] RICH-II planar mirrors stored in DSG small cleanroom

Hello,

This morning, Mindy and I moved the planar mirrors for RICH-II into the DSG small cleanroom (photos attached).

All eight mirrors' packaging were intact and showed no signs of problems from shipping.

The mirrors were left in their silver, packaging exterior bags.

Mirrors B2-R02 and B2-R03 were placed securely leaning against a table due to their longer packaging lengths (this is how the spare mirrors from the first RICH were stored; silver bag on left of that photo).

All other mirrors were stacked in their packaging under the old reflectivity test station's table.
