Removing the S-Lens and Exit Lens (TSQ Vantage)
You must remove the S-lens and exit lens from the ion source interface cage before they can be
cleaned.
To remove the S-lens and exit lens from the ion source interface assembly
1. Wearing clean, lint- and powder- free gloves, loosen and extend the two thumbscrews that
secure the S-lens to the ion source interface cage and the exit lens to the S-lens. See
Figure 48.
2. Grasp the two thumbscrews and carefully pull the S-lens straight out of the ion source
interface cage. Place it on a clean, lint-free surface.
3. Remove the exit lens from the S-lens and place it on a clean, lint-free surface.
