<p class="MsoNormal">At UHNF, each user owns their own sputtering target. We are currently considering a shared model for expensive targets like Au, Pt, etc. Does anyone have a reasonable way to estimate material usage vs something we can track so that we can
charge fairly? What approaches do y’all take to manage how expensive material is shared?<o:p></o:p></p>
