systems with both Faraday and Secondary Emission Multiplier
(SEM) detectors.
As both detectors are off-axis, a deflection voltage is applied to
divert the ion beam into the selected detector. Deflector voltage
settings for both detectors are optimized on this tab.
The SEM voltage can be adjusted (i.e. calibrated) to set a specified
gain (typically 103 or 104).
