(Figure 7–11) allows for adjustment and setting of
Cabinet temperature: Within the range 10°C to 35°C.
Electronics temperature: Within the range 10°C to 45°C.
System pressure: Typically 5 x 10
dependent. Refer to installation records for setting of
optimum pressure.
Ion energy: Approximately 1000 V (for 150 amu mass range)
or 800 V (for 200 amu mass range).
Electron energy: Typically set to 70 V.
Filament current: Depends on filament type:
2.4-2.9 A for a Thoria coated iridium filament

1.5-2.5 A for a W/ThO coiled filament

3.0- 3.8 A for a Re filament

Note If filament is close to zero, check that Trap Current is
set to at least 20 µA and EE is at least 50 V.
