Using the HSA
T1 - T10 Tube numbering
IH / OH Inner / Outer hemisphere
IHP / OHP Inner and Outer Jost-Plate
Ep / Ek Pass energy / kinetic energy (the workfunction should be
set to zero to set the ground plate potential to the difference
between the kinetic energy and the pass energy)
Coil Current PIN 12 can be used to feed the current to the trim coil of the
outer hemisphere (for details see the chapter Magnetic Shielding in
the Phoibos-Manual).
RR Retardation Ratio: Ek/Ep

The following hint is only needed if the above table with fixed kinetic energy and
pass energy does not fit your needs.
2.3.3 Checking the Analyzer Voltages with Custom Setttings
The SpecsLab2 software suite also includes a small batch file called “getVoltages.bat”
located in the tools.bin directrory, this is in the same place located as the diag tool.
This program allows to output the voltages to ground for all possible combinatins of
Ep,Ek and detector voltages for all lens modes.
To use this script a installed version of the GNU AWK Interpreter is necessary. This
can be installed from the SPECSLab2 CD or can be downloaded from
http://gnuwin32.sourceforge.net/packages/gawk.html
Open getVoltages.bat in your favourite editor and adjust at least kinetic energy, pass
energy and lens mode. Then call the script “getVoltages.bat” by double clicking it
from the explorer. The script outputs the voltages at each PIN of the 12-Pin feed-
through and also the detector voltages.
Note: The Screen voltage is only available from the power supply for CCD and DLD
detectors.
