[dsg-hallb_rich] Place to move spare Hall B RICH planar mirrors for long term storage?

[Tyler Lemon]

Hi Walt,

We have four, large planar mirrors from Hall B RICH currently in EEL 121b, the DSG small cleanroom.

That cleanroom is being cleaned out for EIC, but the collaborators would like to keep the mirrors (see Marco M.'s email below).

Is there another place we can store these mirrors?

The only requirement for the storage space is that it be climate controlled so the mirrors aren't sitting in the outside heat/cold/humidity.
Since 2016, the mirrors have been stored vertically in mylar bags with Styrofoam padding (photo attached; mirrors are in the silver bags) and should be stored like that where ever they move.

Thank you in advance for your help!

-Tyler

Dear Tyler,
please do not dispose of the mirrors, they are spares of the RICH that
we want to keep stored safely.
As for the fans, I guess you have to ask Valery.
Marco
