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).
