25 yr old insulation with 25 KV going thru a sharp bend. You can
imagine the result. We just cut the cable, redid the connection and
increased the radius of the bend.

Normally we do not want adhesion to the piece being sputtereed onto.
If we did, we would use Cr to make gold stick. We want the Au (or Pd,
or Pt, etc.) to be a release layer for a subsequent electroformed layer.
