Subject: [labnetwork] Ti Sputtering with a Lesker Torus MagKeeper without a backing plate
Hello all,
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).
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.
Does this make sense? Does anyone have experience with sputtering Ti in a Lesker tool?

Dear Tucson,
Will it sit nicely in the MagKeeper gun without sliding off? As far as I
understand, if the target slides to the side then you'll get a short
between the cathode and anode through the Ti target, resulting in your
plasma extinguishing. If it doesn't slide, then it probably works; however,
I would get a new target for long-term use.
I would be curious about the outcome.
