<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>
