Ion source
better of the two filaments, run two autotunes, one with each filament. Use the fil-
ament that gives the best results.
Emission current
is variable between 0 and -315 µA, but
The filament emission current (
Emission)
should be set to the software default for normal operation.
Electron energy
The electron energy (
EleEnergy
) is the amount of energy on the ionizing electrons.
The electron energy is determined by the bias voltage; -70 V dc bias on the fila-
ment causes emitted electrons to possess -70 eV (electron volts). This value is
adjustable between -5 to -241 V dc, but for normal operation, set this parameter to
70.
