Abstract:

This note is intended to compile thoughts on building, installing, and maintaining upgrades to aLIGO suspensions.

We had in mind the upgrade configurations proposed in G1500233 and G1500246, both warm and cryogenic respectively.

This came out of discussions at the March 2015 LVC in Pasadena.
