Operation of the FEI Tecnai F30 Polara
(22/03/2016)
Initial Checks
1.
Ensure the following software applications are all running and open in
this order:
-‐
Tecnai User Interface
-‐
Filter control
-‐
Digital Micrograph
-‐
TEM Imaging and Analysis (TIA)
If you need to restart the software close all programs and restart in the
above order. Sometimes logging out and back in again can sort out bugs.
The username is supervisor and the password is f30d316
2.
Check the vacuum. The Gun should be at Log 1 and the Column at Log 6.
The Camera should be below Log 35.
3.
Make sure the High Tension is ON (High Tension button Yellow) and the
FEG is ON (Operate button is Yellow).
4.
Check the LN2 levels in the inner and outer dewars. The inner dewar (He
dewar) should be between 13-‐14 (left display) and the outer dewar
should be above 70%. The inner dewar needs topping up every 2-‐3 days.
The outer dewar will empty at a rate of ~5%/hour and should not go
below 20%.
5.
Use the metal funnel to top up the Insertion Rod dewar. This dewar can
last up to 10 hours. If the Insertion Rod warms up the vacuum
deteriorates and the HT may switch off. When collecting with EPU a LN2
top-‐up at 11pm will ensure it stays cold until 9am the next day.
6.
Check the temperatures of the different channels on the display:
1. Helium cryo shield
2. Nitrogen cryo shield
3. Helium cold finger
4. Nitrogen cold finger
5. Guide tube
6. Insertion rod
7. Selection rod
7.
If the specimen Selection Rod is still attached to the microscope, move it
to the transfer station
-‐ Make sure column valves are closed.
-‐ Vent airlock
-‐ Under Setup -‐> Helium -‐> Vent airlock
-‐ Wait for message to close valve B
-‐ Close valve B (Pull out a bit, then push all the way in to lock)
-‐ Wait for message to close valve A
-‐ Close valve A (Pull out a bit, then push all the way in to lock)
-‐ Detach the temperature lead via the USB connection
-‐ With one hand on the plastic manipulator at the base, release
clamps, rotate and lift off hinges, move over to the transfer station
-‐ Place on hinges, rotate flush, fasten clamps
