<p>Dear Network,</p>
<p>We have inherited an old XPS machine. The XPS part works fine
and we know how to acquire data. For analysis, we will certainly
consult experts before publishing as we are aware of the potential
pitfalls. </p>
<p>We also have an Argon source and sputter power supply and we
would like to sputter our sample surfaces to remove surface
contaminants. The problem: we are neophytes at that part of the
process besides operating the cylinder and leak valve.</p>
<p>My question: What are the typical Ar pressures and power settings
generally used for sputtering?</p>
<p>Please respond privately or through the network.</p>
<p>Big THANK YOU.</p>
<p>Mario</p>
