<div dir="auto">You absolutely need a magnetic keeper, but Cu backing isnt mandatory. <span></span></div>
<div dir="auto">What I did in exact same situation was drilling a hole in a target to 3/4 depth (used lathe for centering) and threaded it with a bottoming tap. Then screw keeper to target using a vacuum screw.</div>
<div dir="auto">Gluing a keeper with epoxy or a through hole with Ti screw are other options. </div>

<p class="x_MsoNormal">Hello all,</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">I have a Lesker PRO-Line Sputter tool and the guns have Torus MagKeepers. I have a student that would like to sputter Ti. I have a Ti target, but it doesn’t have a backing. All of my other targets have backings. It seems logical that
if I want to use a target on a gun with a MagKeeper I would need a backing (pictured is my Al target with a backing).
</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">I asked our Lesker sales rep and his response was to use the Ti target without the backing. I asked if the target will slide off of the gun. His response was no.</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">Does this make sense? Does anyone have experience with sputtering Ti in a Lesker tool?</p>
<p class="x_MsoNormal"> </p>
