Automated hv-scan

Controlling monochromator via software to measure kz dependence

First you need to make sure that auto beam-position control is working.

To perform an automated photon energy scan:

• In the MultiAx window open tab "Mono corrections"

• Tick activate

• In the CommPort | MONO block check that COM2 is selected and click Connect.

• Check the current photon energy, the value should appear in the yellow box (Position [eV])

• In the SES window create a new CIS region, press Edit, set start/fin values of hv and step

In CIS mode energy values are set as Binding energy! E.g. Fermi level is around 4.5 eV.

Before starting a scan make a test run and make sure that the intensities are reasonable at all photon energies in the range. Ideally one can adjust the intensity manually for each photon energy by the beamline exit slit or beamline apertures.
