The diffusion pump is the most common type of pump for use in high-vacuum applications. These vapor jet pumps are one of the oldest and most reliable ways to create a vacuum. Since the chamber itself has no moving parts aside from the oil droplets, a vacuum diffusion pump can operate with stability over long periods. In all diffusion pumps, a small amount of backstreaming occurs. Backstreaming is the migration of minute levels of oil that move in the opposite direction, toward the inlet of the pump and into the process stream, which may be the stage of an electron microscope or a welding chamber. In some applications, minor backstreaming has no impact; in others, where the purity of materials is critical, backstreaming cannot be tolerated. For this reason, systems typically add an optically dense baffle of varying design to deflect oil particles before they can reach the process stream. Diffusion pumps are in wide use because they have several advantages: They are reliable, simple in design, operate without noise or vibration, and are relatively inexpensive to operate and maintain. In fact, diffusion pumping is still the most economical means of creating high-vacuum environments. These pumps also tolerate operating conditions such as excess particles and reactive gases that would destroy other types of high-vacuum pumps.
