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/end values of hv and step

In CIS mode energy values are set as "Binding energy" (hv-E_kin)! Fermi level will be 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!
