According to our present understanding, the early Universe contained the same amount of matter and anti-matter and, if the Universe had behaved symmetrically as it developed, every particle would have been annihilated by one of its antiparticles. One of the great mysteries in the natural sciences is therefore why matter dominates over antimatter in the visible Universe. The breaking of the combined charge conjugation and parity symmetries (CP-violation, CPV) in the Standard Model of particle physics (SM) is insufficient to explain this and further sources of CPV are sought. These could manifest themselves in electric dipole moments (EDMs) of elementary particles, which occur when the centroids of positive and negative charges are mutually and permanently displaced.

The EDM measurement principle, the time development of the polarization vector subject to a perpendicular electric field, is simple, but the smallness of the effect makes this an enormously challenging project. A stepwise approach, from R&D for key-technologies towards a double-beam precision storage ring with two counter-rotating beams is needed. The research environment of the Forschungszentrum Jülich (Germany), including the storage ring COSY, provides the optimum basis for such an experimental programme carried out by the JEDI collaboration ( We have the following openings for PhD positions.

Commissioning of radio frequency Wien filter and first measurement of deuteron EDM:

The new team member will be working on a new experiment using an RF Wien filter to measure the deuteron EDM at the COSY storage ring. The assembly of the RF Wien filter is presently underway and the device will be installed at COSY at the end of April 2017. The immediate aim of the work is to bring the device to full operation during two commissioning runs at COSY during 2017 and to perform a first measurement of the deuteron EDM in 2018.

Development of beam position monitor system
The EDM measurement requires precise knowledge of the beam properties to minimize systematic uncertainties. The beam position can be measured with so called Rogowski coils. First measurements with prototypes were performed. The PhD thesis comprises the further development of the prototypes, test measurements at COSY, simulations to investigate the number and positions of BPMs needed for the EDM measurement.

Your profile:

  • A master's degree or diploma in physics or electrical engineering.
  • Strong motivation to study fundamental physics and to develop new experimental techniques
    and approaches.
  • Good hardware skills. Experience with storage ring experiments would be advantageous.
  • Programming skills and experience with numerical modeling methods and data analysis.
  • Team spirit.

Starting date:
April 2017 or later. Applications are accepted until the positions are filled.
