3 Operation
If you are not familiar with the 2D-CCD / 3D-VLEED detector, it is recommended that you
read Chapter 5, “
Spin detector principles ” before continuing.
The 2D–CCD / 3D-VLEED Detector effectively consists of three detectors in one:
1. A CCD detector capable of measuring spatial and dispersive dimensions.
2. A VLEED Spin detector capable of measuring 3D spin polarization.
3. A single channel detector capable of measuring the total intensity reaching the
VLEED spin detector.
In SpecsLab Prodigy, the PHOIBOS analyzer together with each one of the detectors is
available as an analyzer. Thus, there are three analyzers:
1. PHOIBOS CCD. With CCD detector.
4. PHOIBOS Spin. With VLEED spin detector
5. PHOIBOS 1D. With VLEED total intensity detector.
Switching between one operation mode and the other is simply a matter of selecting the
analyzer in the software.
Note
Before taking measurements, you need to be sure that SpecsLab Prodigy is correctly
configured to use your excitation source, e.g. by configuring an X-ray dummy source. Further
details are provided in the PHOIBOS and SpecsLab Prodigy manuals.
In addition to describing normal operating procedures for the detector in spin and CCD
modes, this chapter also describes the procedure for finding the optimum detector voltage
for the Ferrum detector.
3.1 Using templates to set up experiments
SpecsLab prodigy offers templates, pre-defined experiments or fragments of experiments,
which you can use to save common tasks. A number of templates are included with the 2D-
CCD / 3D–VLEED Detector. The following sections describe the purpose of each of the
templates and their contents.
The procedure below shows the basic procedure for using templates. See also the SpecsLab
Prodigy Quick Guide and Online Help for more information.
