Couldn't one create a ring around a tube with coper wire for this
purpose? I was thinking small wire wrapped around the tube about the
size of a wedding ring?

What is the best spot on the tube (just below the getter?)

CTE mismatch is likely to be the problem here.
If you cant maintain tight coupling to the tube...it won't function
as a damper and may make things worse.
Copper is not often used as a damping material.
