B-28 The MassLynx Tune window
Note: Filament Current (A) is a readback only.
Outer Source pane
Beam Steering The beam steering applies a voltage to one side of
the focus lens and reduces voltage on the lens’
other side. This redistribution of voltage to
change the lens angle effectively steer a beam left
or right.
The readback from one side of the focus 1 lens
appears in the left field of the two Beam Steering
fields. The readback for the other side of the focus
1 lens appears in the left Focus 1 field. The read-
back values appear in red.
Focus 1 Voltage on the first focusing lens.
Focus 2 Voltage on the second focusing lens.
Focus 3 Voltage on the third focusing lens.
