11. Place the locking ring on top of the repeller spring so that the repeller protrudes through
the center hole on the locking ring. The hooks on the sleeve fit between the larger gaps on
the locking ring.
Note Do not twist and lock the locking ring on the sleeve at this time.

IMPORTANT When inserting a cold ion source cartridge such as after cleaning or when
switching between EI and CI modes, the ion source and lens stack will expand as the
source cartridge heats, often pushing the ion volume and lenses away from the rear of the
instrument where they are firmly held by the RF Lens spring contacts. To avoid
intermittent electrical contacts to the lenses, you should insert the ion source cartridge,
wait 30 minutes for it to get to temperature, then remove and reinsert it.
 To reinsert the ion source cartridge through the vacuum interlock
1. Hold the source holder and ion source cartridge in one hand and use the other hand to
hold the ion cartridge tool so that the barrel is facing toward the floor. The diagram on
the tool should be facing you.
IMPORTANT If you try to attach the ion source cartridge to the tool by inverting it,
the components will likely fall, so make sure you are working over a table. Otherwise,
you may have to stop and clean the components again.
