We offer two post doc position in the Section of Plasma Physics and Fusion Energy (PPFE) at the Department of Physics, Technical University of Denmark. 


Job description
You will take part in the research in the section for Fusion and Plasma Physics, encompassing activities in plasma turbulence, microwave physics and ion dynamics. Your research will be within the activities on parametric decay (PD) of plasma waves. Specifically, you will work with the interaction of high-power waves in the Electron Cyclotron range produced by gyrotrons and magnetrons. The work is inspired by the observation of powerful microwave burst produced at the facilities Wendelstein 7X, ASDEX Upgrade and TEXTOR during strong microwave heating. First theoretical studies indicate that a significant fraction of the heating power may undergo decay and thus, partly, explain the low energy confinement times observed in magnetic confinement fusion experiments.

The job opening concerns two positions which focus on experimental or/and numerical work within the PD activity at PPFE. The activity currently consists of two senior scientists, 2 PhD students, a technician and several undergraduate students.

A large part of the experimental work will be to characterize and understand the interplay between waves produced by the PD processes and assess the depletion of the original ECRH waves. The experimental work will include the daily supervision of the DTU NORTH tokamak experiment and mentoring of PhD, MSc and BSc students.  Development of, and participation in experiments on larger European fusion facilities, data analysis, modelling of microwave propagation, emission and absorption in plasmas and comparisons with experiments is also a part of this work.

The numerical work includes supervising the numerical effort of wave-plasma interaction at DTU. Topics to be investigated compose the decay of Electron Bernstein waves into Ion Bernstein waves, damping of Ion Bernstein waves on thermal and non-thermal particles and the propagation of helicon waves in the NORTH tokamak. The work will also include supervision of students and running numerical codes for plasma-wave interaction, such as the Particle in Cell code EPOCH.

Qualifications
You should have a PhD degree in Physics or equivalent, the ability to work in teams and strong communication skills in English. Experience with al least one of the following topics is required: 

  • General plasma physics
  • Simulation experience of microwave / plasma interaction
  • Plasma instabilities
  • Microwave radiometers
  • Electron cyclotron resonance heating
  • Labview or Matlab/python experience
  • Plasma diagnostic systems

We offer

an exciting and challenging job in an international environment with good possibilities for professional and personal growth. 

Salary and terms of employment
The appointment will be based on the collective agreement with the Confederation of Professional Associations. The allowance will be agreed with the relevant union. The period of employment is 2 years.
