The JSM-7000F is a field-emission scanning electron microscope with a Schottky type field-emission gun for the electron source. The instrument is equipped for energy dispersive X-ray spectroscopy (EDS).
Check the nitrogen bottle pressure on the regulator (gauge closest to the bottle valve) must be above 2000kPa. Do not adjust the regulator or close the bottle.
Remember the bottle pressure for adding to the instrument log when you get to that point. |
Use the IR-camera to confirm that:
Infrared camera view showing empty stage, no holder, and in approximate exchange position
Select the "Display Camera Input" option from the software toolbar Turn on the power to the camera |
Verify the exchange chamber buttons EVAC and EXCH POSN are lit and and the HLDR is not lit
|

Use gloves to handle any items that are to be used in vacuum. Grease from hands is a major source of contamination under high vacuum. |
The holders are shown below:
12.5mm | 32mm | 3WH |
---|---|---|
2BH | SM71270 |
Measure to the nearest millimetre the distance from the top of the sample holder to the top of the tallest sample on the holder. You will enter this value into the software as the sample offset. It is better to be conservative if an accurate measurement cannot be easily acquired |

Only hold the rod by the black handle. The rod itself is coated in grease to form a seal during the transfer operation |
Lay the rod down horizontally, when the end drops off the hinge it will spring forward. Hold the handle to control the spring.
Tap the end of the handle to ensure correct compression of the carrier seal
Push the rod until it is fully inserted. There will be slight resitance towards the end as the stage carrier springs are extended
Wait for 3 seconds until the HLDR light is lit
Fully retract the exchange rod. Continue pulling the rod horizontally until the end reaches the arrows on the hinge bracket
The Penning vacuum gauge on the software should return to non-zero value after a few seconds if the vacuum hasn't been interrupted during the transfer
Sample exchange is complete
Select the holder type from the Stage specimen Holder exchange
Enter the "specimen surface offset" in the lower half of the form. You have to press enter after entering the value otherwise it won't be modified.
Ensure the IR-camera is powered on and the signal is displayed on the SEM software |
