VLEED spin detector 5.5
For information about the Ferrum spin detector and its principle of operation, please refer to
the Focus Ferrum Spin Detector manual.
PCU 300 Electronics 5.6
The PCU 300 is mounted directly onto the CEM flange of the Ferrum detector, in order to
receive the signals from the CEMs without any cable losses. It serves as a counter and
preamplifier.
The PCU 300 is a SPECS design. The Focus Ferrum Spin Detector manual describes a different
design. You should bear this in mind when reading the Focus Ferrum spin detector manual.
Example of experimental results 5.7
Graphene on Ir(111) has Rashba split surface states with opposite spin.

In addition, the
system is stable enough to be exposed to air. This makes it suitable as a test system for spin
detectors. In the experiments described below, ARUPS with HeII excitation (excitation energy
