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

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

Is there another place we can store these mirrors?</div>

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.</div>

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.</div>

<div style="font-size: 11pt;">Dear Tyler,<br>
please do not dispose of the mirrors, they are spares of the RICH that<br>
we want to keep stored safely.<br>
As for the fans, I guess you have to ask Valery.<br>
