Beam Current Setting
Use this guide for electron transparent samples and for bulk samples when a picoamperemeter /
beam current monitor is available to measure the beam current.
Step
Example/hints
1
Measure beam/ probe current.
Use a Faraday cup or a calibrated electron
screen.
2
Load or create a standards library.
Follow section 5.11.1 for bulk samples or
secti
ons 5.11.2 and 5.11.3 for electron
transparent samples.
3
Click the Standards configurator’s
calibration icon
to open the
S
YSTEM FACTOR CALIBRATION
dialog.
4
Enter probe/beam current value manually
in the System factor field and press
<Enter>.
For Zeta quantification of electron transparent
samples, the probe current needs to be
known and entered in pA.
5
the SYSTEM FACTOR
CALIBRATION
dialog.
The system factor is now updated with the
beam/probe current and measured spectra
will contain this information.
