Assemble the repeller assembly, by attaching the repeller to the repeller
cap and connecting the clocking button with the screw.
Align the heater sensor with the source body.
Slide the repeller cap onto the heater sensor, and place the ceramic
repeller insulator on top, aligning the screw holes.
Place the RIS bayonet mount on top of the ceramic repeller insulator, and
attach with the washers and screws.
Attach the extractor lens insulator to the extractor lens, and slide them
onto the other end of the source body
Place the ion focus insulator on the ion focus lens and attach with the two
screws.
Set the ion focus assembly on top of the extractor lens assembly on the
source body.
Attach the filaments with the two screws.
