Sputtering Magnetron

A few important developments this past weekend:

I upgraded the vacuum chamber to a larger size. I picked up a nice 5" round glass vase from a local craft store.  From left to right is the current progression of chambers so far. The far left original chamber was too small and had only a single passthrough for both the vacuum and high voltage. It ended up getting way too hot way too quickly. The middle chamber was suffered from a crack due to running the device too long and generating heat that wasn't dissipated. 

Another development from the weekend was that I decided to research magnetron design and to construct a sputtering head that will be in the chamber. Using what I learned from various papers and from watching the "Applied Science" channel video on Sputtering - I designed and 3d printed a sleeve that was used to create a metal casting for the magnetron. 

Shown above are some various parts of the disassembled sputtering head. Hopefully it will all come together this week.

Had my first failure. After running the device too hot and too long, I heard a snap! I was able to turn off the vacuum before an implosion. Now I need to build another vacuum chamber. Two steps forward, one step back!
