Several instruments in our lab work in vacuum environments. For example
If using these systems, there are some basics about vacuum technology that you need to know. Our lab has a copy of “A User's Guide to Vacuum Technology” by John O'Hanlon. This book is an excellent resource.
I'll collect a few classic “rules of thumb” on this wiki page:
Where P is the pressure in Pascals. (1 atm = 10^5 Pa = 760 Torr).
Pressure | Mean free path |
---|---|
760 Torr | 65 nm |
7.5 x 10-6 Torr | 6.6 m |
