[dsg-hallb_rich] [EXTERNAL] rich activities

[Tyler Lemon]

Hi Marco,

I haven’t been into the lab in person since receiving the aerogel, but I am going in this afternoon so will check the tile then.

I have not heard anything further from CMA on the mirror shipment.
I submitted the authorization form and talked to JLab shipping & receiving about the shipment and the insurance for it and they’re already started the process, so hopefully it won’t take too long to pick up the mirrors after we get the dimensions.

I’ve found most of the components through US companies. The exceptions are the bolts made of PEEK. I cannot find black-colored components either. Do those parts need to be made of PEEK, or would other types of plastic be okay (I’m assuming metal components are not okay)?

-Tyler

Hi Tyler,
could you update on on the RICH activities we discussed last week, in
particular:
1) Did you have a chance to have a better look at the damaged tile
445f37? If we need to buy a replacement, I would do that as soon as
possible, so that it can be shipped together with the last batch of
tiles.
2) Last news I got from CMA last week about the mirror shipment was that
they were preparing the material. Did you get anything more?
3) What is the situation with the purchases of the small parts for the
mirrors? This is material that should be shipped to CMA together with
the two mirrors after the tests.
Thank you,
Marco
