Work location is at the TCV tokamak located at the EPFL in Switzerland.

Incumbent will be responsible for obtaining a visa and for moving expenses.


This position encompasses data taking and analysis using a Langmuir probe array system already installed by UCSD at the TCV tokamak in Switzerland. The job includes operating, maintaining and upgrading the existing probe system, which is comprised of 9 tips with different functions such as single and double Langmuir probes, a Mach array, floating potential measuring arrays, etc. The Langmuir probes are powered by a variety of power supplies, from DC (500-600V ) to AC (500-600V at 1 kHz) to low RF (100 W at 500-1000 kHz).

The incumbent will participate in software development and utilize existing software to extract information from the signals obtained, plasma temperature and densities, plasma potential and plasma velocity, radial and poloidal electric fields, among others. The data above will be combined to calculate ExB drifts, fluctuation levels and the resulting turbulent transport.


  • Demonstrated knowledge of physics and engineering. Working knowledge of research function.

  • Must be bilingual in French and English.

  • Working skills in statistical analysis, systems programming, database design and data security measures. Knowledge of software design for existing probe.

  • Proven experience in plasma physics, tokamaks and Langmuir probe design and operation and data analysis. Experience with IDL, Python, Mathlab.

  • Demonstrated knowledge of Langmuir probe theory, single and double probe codes, harmonics technique.

  • Demonstrated knowledge of tokamak equilibria reconstruction, such as EFIT or LIUQE. Familiarity with Fusion plasmas.
