Ion Gauge
An ion gauge measures the pressure inside the vacuum manifold and produces energetic
electrons to ionize molecules. Positive ions formed in the ion gauge are attracted to a collector.
If you have an ion gauge, it must be powered on and the pressure must be less than
1x10-3 Torr to turn on the filament, electron multiplier, or conversion dynode. This pressure
setting protects these components from being damaged.
To install an ion gauge
1. Shut down your system by following the steps in
“Shutting Down the ISQ System”
2. Use a T20 Torxhead screwdriver to loosen the top cover panel screws from the interior
front panel. Then lift the top cover panel off the instrument.
3. Use a T20 Torxhead screwdriver to remove the screw at each outside corner of the right
side panel.
4. Attach the ion gauge shield and tube to the board, as shown in the figure below.
Figure 448.
Removing the Right Side Panel
Note
The metal tube can be placed on the board in two different ways. Only one of the
orientations will allow the tube to attache correctly to the manifold.
