New high vacuum system

I'm building a physical vapor deposition rig, which will be an interesting tool for creating optical coatings, SEM sample preparation, and maybe even thin film transistors. So far, I only have the pump and Penning gauge connected to the chamber. Soon, I'll have high-current and high-voltage ports in the base plate for controlling the deposition process.


  1. nice projekt - respect!

  2. Fan spam!

  3. You might consider adding a cold trap, you can use dry ice and acetone as the coolant, or if you are feeling rich get some LN2

  4. When it comes to the vacuum cleaning machines, of course, everyone wants to get the most economical and multi-functional one. You must have a look at professional shark navigator lift away reviews that will properly demonstrate this particular cleaning device, its features, pros, cons, specifications and a lot more.
