Mr. Peter John Smith:
After looking your reprints of diffusion pumps, I can
see all of them have ejector as the last stage.
I wish to know where are the benefits of the ejector
system and also the problems it can bring.
Do you have a close drawing of the ejector, with
dimensions and critical details.
I am glad you are all ears, if anyone else has more
info on actual dimensions and construction of a diff
pump.
Thanks you.
Albert Gasparini
