Operations
Loading a sample
1. Mount the sample with fast drying adhesive medium onto the stub. Allow to dry.
2. Check the sample satisfies the sample limits imposed by placing the top of the mounting tool over the base
mount.


If the sample proves to be too large this has to be addressed before the sample and carrier are allowed into the loader
chamber.
3. If the sample satisfies the limits, the sample loaded carrier can be loaded into the loader chamber. A user can
either remove from or place a mounted carrier in the loader chamber by using tweezers for stubs which will fit
around the stub rim.
Note

Loading samples this way is an easier and safer than trying to mount the sample directly into the sample carrier while in
the loader chamber.
Rod Loading Sequence
1. While holding the sample carrier on the loading table in the
loader chamber move the rod out of the Parking position to the
far left, to the back of the slot and forward to engage the
bayonet into the sample carrier. Place the rod back into the
Parking position after coupling to prevent the rod slowly
creeping forwards.
2. Switch off the electron and ion beam accelerating voltage.
Retract the GIS, Omniprobe, EasyLift or STEM modules (if
present) to a safe state (cannot be used in combination with
loader).
3. Close the loader chamber lid. After the lid is properly closed
the
P button starts to shine.
4. Press the P button, the button stops to shine and the pumping
cycle starts, the stage moves to the loading position at the
same time. When the vacuum in the loader chamber is correct
the pump light starts to shine and the
OK button lights up
indicating operation can continue. The gate valve lever
interlock is released.
5. Turn the Gate Valve knob lever from LOCK to UNLOCK
position. Then carefully pull the knob bar fully out from the
first mark on the knob drum to the second mark. Turn the knob
bar (counterclockwise) to the LOCK position.
6. Move the loading rod from the Parking position into the
chamber while still holding the rod bar. The Sample Carrier will
engage with the Stage Adapter at the end of the rod travel.
7. Turn the rod bar to the left (counterclockwise) to the base of
the slot; pull back on the rod bar so it travels along the base of
the slot, then turn to the right (clockwise) so that the rod bar is
vertical and withdraw it back to the PARK slot at the far end of
the rod guide.
8. Close the Gate Valve by turning the knob bar to the UNLOCK
position and press the knob in to engage the valve over the opening, this can be seen through the lead glass lid,
then turn the knob bar to the LOCK position to secure the valve. Good practice is to leave the loader chamber
under vacuum.
