Hi everybody,
I'm a new guy in the group. I joint this, because I have serious plans to build my own vacuum-chamber (10E-5 to 10E-7 mBar).
I decided to go with a diffusion pump and a system as already decribed by "atm_ken_hunter" under the "Files" section in this group.
Following link shows a screenshot of the basic concept I want to build (taken out from the File posted by "atm_ken_hunter"):
In that concept a "baffle" is indicated. I wonder, how such a "baffle" looks like, how complicated it is, how it works and functions etc.
I am even more curious about that "baffle" because in Ebay is an auction, where somebody points out, that he is selling a diffusion pump together with a "baffle" and that the "baffle" alone would already costs 2000.- Euro (approx. 2500.- US$ !!!).
Wow, something that expensive was not on my bill-of-material list so far.
Where can I learn more about "baffles", their function and design, and how to get a or build a "cheap" one.
Thanks everybody for your support.
Cheers
Alexander
