Area: Faculty IV: School of Science and Technology  | Job scope: part-time  | Duration of employment: limited  | Posting-ID: 4882

The University of Siegen is a modern university with an international orientation and a focus on interdisciplinary research. It currently has around 16,500 students and covers a range of research fields from the humanities, social and economic sciences to natural sciences, engineering and life sciences. With over 2,000 employees, the university is one of the largest employers in the region and offers a unique environment for teaching, study, research and knowledge transfer.

Place of employment:

DESY, with more than 2,700 employees at its two locations in Hamburg and Zeuthen, is one of the world’s leading research centres. Its research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. With its ultramodern research infrastructure, its interdisciplinary research platforms and its international networks, DESY offers a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists.

About the research group:

The X-ray tomography group is based on a collaboration between the University of Siegen and DESY. Our goal is to combine the expertise in material- and nanosciences at the University of Siegen with the latest analytical X-ray methods from PETRA III in Hamburg.

About the project:

The aim of the project is to significantly improve the experimental setup for X-ray diffraction with high spatial resolution at the P06 beamline of PETRA III and, thereby, establish this setup at the forefront of international research in this area. This will be achieved by reducing scan times by a factor of 10 and, simultaneously, provide a spatial resolution of 100 nm. Recent experiments demonstrate the feasibility (J. Synchrotron Radiat. 29, 1407, 2022). In addition, a software package for automatic data analysis is to be developed. This method should then be applied to current questions in modern solid state physics (e.g. efficiency of thin-film solar cells or short crack propagation in spring steels).

We seek:

At the Faculty IV: School of Science and Technology, in the X-ray Tomography Group of the Department of Physics with the working location DESY (Hamburg) a

PhD candidate (m/f/d)
(75% = 29,87 hours Teilzeit, salary category 13TV-L)

is to be hired for 3 years at the earliest possible date.

Successful application is subject to the provisions of the Act on Temporary Employment in Higher Education (§ 2 Para. 1 WissZeitVG).

The successful candidate will participate in the project “High speed X-ray nano-diffraction (HS-XRND)”, which is funded by the German Ministry for Education and Research (BMBF-Project: 05K22PS2).

Your tasks:

  • Upgrading and commissioning of the diffraction goniometer at beamline P06
    at PETRA III
  • Performing experiments with collaborators in the area of HS-XRND
  • Development of an “online” data analysis software package for rapid feedback
    during experiments
  • Improve quantitative data interpretation by advancing the physical understanding
    of HS-XRND

The position is intended to facilitate the acquisition of a PhD.

Employment requirements:

  • A diploma or master’s degree in Physics (or related subjects) with an excellent
    final mark
  • Experience in using scientific programming languages
    (Python, MATLAB, C++ or similar)
  • Experience with X-ray experiments preferably at Synchrotron facilities
  • Profound knowledge in X-ray science and/or solid state physics

In addition:

  • Fluent English skills
  • The ability to do team-work in an international scientific collaboration
  • Experience with the development of scientific instruments

Our range of services:

  • Diverse opportunities to take on responsibility and make a visible contribution in the research and teaching environment
  • A modern understanding of leadership and collaboration
  • Good work-life balance, for example, through flexible working hours and work location, as well as support with child care
  • Extensive personnel development program
  • Health management with a wide range of prevention and counseling services

We look forward to receiving your application by 12.04.2023.
