Chapter 3: Review of Basic Vacuum Calculations
asiavacuumpumps.comVacuum technology is based upon the creation of an environment in which a process (thin film deposition, electron beam welding, etc.) can be carried out. This normally implies that one remove air from a system to some acceptable sub atmospheric pressure by the use of some type of vacuum pumping equipment.
Understanding Vacuum and Vacuum Measurement
solarmfg.comHigh Vacuum – is vacuum where the MFP of residual gasses is longer than the size of the chamber or of the object under test. High vacuum usually requires multi-stage pumping and ion gauge measurement. NASA has revealed that the vacuum level recorded on the moon was 1x10-9 Torr. 1 Ultra-High vacuum – requires baking the chamber to
