Vacuum Manifold
The vacuum manifold encloses the ion source interface, ion optics, mass analyzer, and ion
detection system assemblies. The vacuum manifold is a thick-walled, aluminum chamber with
two removable side cover plates, with openings on the front, sides, and top, and various
electrical feedthroughs and gas inlets.
The vacuum manifold is divided into four chambers by three baffles. See Figure 31. The
forepump evacuates the region inside the first chamber, called the ion transfer tube/skimmer
region. The third inlet in the molecular drag section of the triple-inlet turbomolecular
vacuum pump evacuates the region inside the second chamber, called the Q00 ion optics
region. The interstage port of the turbomolecular vacuum pump evacuates the region inside
the third chamber, called the Q0 ion optics region. The high vacuum port of the
turbomolecular pump evacuates the region inside the fourth chamber, called the analyzer
region, to less than 10
–
5
Torr. The turbomolecular pump in turn discharges into the
forepump through the foreline.
