Open Positions


There are two PhD positions immediately available:

FEL based photoelectrons spectroscopy on gas phase clusters

In this BMBF funded project a new mobile cluster photoelectron spectroscopy apparatus especially designed for experiments at FELs will be completed - core components like a special cryogenic low background magnetic bottle spectrometer and a high intensity cluster source exist already - and used for a broad range of experiments on size-selected clusters at FELs like FLASH, studying the structure of shallow core states and ultrafast electron dynamics in lower and higher intensity fields. The experimental setup will be a compact version of the one described here.


Very high resolution photoelectron spectroscopy on size-selected deeply cold metal clusters

In this DFG funded project a recently developed very high resolution magnetic bottle photoelectron spectrometer will be used for photoelectron spectroscopy on deeply cold size-selected metal clusters, using isomer-selective techniques to measure isomer-dependent electronic structures and, for smaller clusters, vibrational frequencies. Of additional interest is a search for finite size precursors of low temperature quantum effects like the Kondo effect or superconductivity. The experimental setup is described here (not yet fully updated).


The candidates are expected to have a strong background in physics or physical chemistry, and ideally experience with vacuum technology, ion beams, laser or x-ray spectroscopy. Good knowledge of German or English, both written and oral, is compulsory.

Apart from these, there are several Bachelor and Master thesis projects available; contact bernd.von.issendorff for details.
