9.5.5 Refitting the PVD / CVD ion source

Refitting the ion-source is simply the reversal of the procedure for removing it. Care should be taken at all
stages to ensure that no shorts are introduced and that the analyser is kept clean.

The orientation of the ion-source is by the small notch on the mounting base. This notch is positioned so
that it sits over the gold leads visible on the filter assembly as indicated below.

Once positioned, slide home the ion-source assembly so that it sits flush on top of the filter, refit the three
M2x4 screws and shakeproof washers and tighten securely.
