Doctoral student Femtosecond Soft X-ray

in synchrotron based Spectroscopy of Matter


spectroscopy under Realistic Conditions
of liquids and solutions

The PhD project forms part of a larger project dealing with the spectro-
scopic investigation of chemical dynamics in liquids and solutions under
the title: “Femtosecond Soft X-ray Spectroscopy of Matter under Realis-
tic Conditions”. The aim is to drive the development of soft X-ray scatter-
ing of electron and configuration dynamics of biological relevant systems
towards a routinely applicable method.
The technology employed is resonant spectroscopy at the K-edges of
Carbon, Oxygen and other chemical relevant elements. This method is
available only at accelerator based light-sources as synchrotrons and the
new free-electron lasers. The PhD candidate will be enrolled at Uppsala
University, and located at MAX-lab in Lund (Sweden). A part of the
experimental work will most likely be performed at other places, e.g. at
BESSY in Berlin, Germany, or SLS/PSI in Switzerland.

Our main focus lies on instrument and method development. The PhD
project will therefore include instrument development through (pilot)
research on prototypical systems.

We are searching for a candidate with a clear motivation to do challeng- 3


ing experimental work in a purposeful way and is not afraid of the level 8 B’ Πg
