 To reinstall the tube lens and skimmer
1. Reinstall the tube lens into the ion source interface cage as follows:
a. Orient the ion source interface cage as shown in
that the lead pin points toward the correct socket in the contact ring support.
b. Insert the lead pin into the socket and firmly press it until it snaps into place.

CAUTION Do not scratch the outside of the skimmer cone.
2. Reinstall the skimmer into the ion source interface cage as follows:
a. Align the skimmer so that the lead pin points toward the socket in the contact ring
support.
b. Insert the lead pin into the socket and firmly press it until it snaps into place.
Chemicals can accumulate on the surfaces of the exit lens and S-lens. The use of an S-Lens
that incorporates an rf electric field, however, minimizes the harmful effects of this
contamination. The exit lens and S-Lens require cleaning less often than the ion sweep cone
and the ion transfer tube. Remove the exit lens and S-lens from the ion source interface cage
before cleaning them. No tools are needed to remove or install these components.
To clean the exit lens and S-lens, follow these procedures:
