Removing the old filament
1.
Remove the six (6) ¼-28 bolts that fasten the quadrupole head 10-pin
feedthrough to the vacuum system.
2.
Remove and discard the copper gasket.
DO NOT TRY TO REUSE THE GASKET.
3.
Position the quadrupole head so that it is pointing up and is secure.
4.
The ion volume on the enclosed source must be removed to replace
the filament. Using a hex wrench, remove the lock screw on the col-
lar holding the ion volume to the source (see Figure 6-2). Carefully
remove the ion volume and set it asi
de.

5.
The filament plate is held in place by two (2) stainless steel rods that
carry the current to the filament. Using the hex wrench provided, loos-
en the two screws enough to rotate the filament plate counterclock-
wise and remove it by sliding the plate over the screw heads (see
Figure 6-2). Be sure to remove all residual pieces of the old filament.
