Target B mount damaged

Metalica Users,

I inspected the mounting surface for target B.  The surface was damaged 
from sputtering using a depleted target.  The mounting surface was damaged, 
but can still be used.  We will need to either resurface or replace the 
target mounting.

If you have a high power deposition, I recommend you use target A.  The 
mounting surface is smoother and will provide better thermal conductivity 
for heat removal.

This was an avoidable mistake.  Make sure the target has sufficient life 
for your deposition.   Not only damaging the system, your samples have also 
been compromised.  You have added both the silver paste and stainless steel 
to your deposited film.
