[dsg-hallb_rich] [EXTERNAL] spherical mirrors

[Tyler Lemon]

Hi Marco,

 I’ll get the mirrors over to shipping and receiving this afternoon.

We’ll start the fabrication of the new mounts soon as well.

Hi Tyler,
we just had a phone meeting with CMA to discuss the issue of the higher
thickness of the mirrors. It looks like the new mounts modified by
Sandro should fix the problem.
Therefore I would ask to
- ship the two mirrors only to CMA as soon as possible, they need the
mirrors to finish the supporting frame
- print the 30 mounts with the new design, as the test one that Brian
printed before we left (but if possible it should be black instead of
transparent)
- once the new mounts are ready, ship them to CMA
Your visit to CMA should be scheduled after CMA finished the frame and
glued the mounts on the back of the mirrors.
Thank you,
Marco
