<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Agree with Steve on keeping the targets. Depending on targets some do require to be kept in inert atmosphere. We had a bad experience
with a Lanthanum target that was left in original package and not in N2 and after a year it degraded (became powder).<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">About the used targets you can dispose of them through regular way of getting rid of chemical products (depending on SDS). Of course
precious materials can be recycled (I used to remove copper plate from Au and Pt by dipping it a concentrated sulfuric acid that fully consumes the copper).<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"> I see no reason to cover the targets at all. Keep in mind that when you begin the process, you are sputtering onto a shutter which reveals homogeneous
material free of oxidation and airborn contaminants. We have always stored them in a plastic food container for general protection from damage and put them in a nitrogen flooded dry box for good measure but I don’t believe it makes any difference. Perhaps
someone else in the network can attest or disagree with my practice since I’m sure that if there are experts in these sciences, they subscribe.<o:p></o:p></span></p>
