Deadline: 19 Jan 2018
Job Code: PD80
The Max Planck Institute for Plasma Physics in Greifswald, Germany, is seeking in the framework of its development program for young scientists for the Stellarator Edge and Divertor Physics Division a graduate physicist for the development and first experimental use of a next-generation neutral pressure gauge.
The neutral pressure is the basic parameter to characterize particle exhaust in nuclear fusion devices. It is generally measured by pressure gauges of the ASDEX type which, however, suffer from a relatively high failure rate when operated at high magnetic field strengths for long times. We have improved the ASDEX design by using a LaB6 crystal instead of a tungsten wire as the thermionic emitter of electrons in the gauge. A first LaB6 prototype gauge has recently shown much improved performance.
The task of the candidate is to bring this prototype design to full maturity. This includes bringing a new test facility with a superconducting magnet with B up to 6 T into operation, and conducting experiments to improve the performance of this gauge, as well as to understand the underlying physics of potential detrimental effects, such as unstable operation points, or long-term fatigue effects, so that these can be mitigated. A successfully tested 2nd generation prototype will be installed in two fusion experiments, the stellarator Wendelstein 7-X in Greifswald and the tokamak ASDEX Upgrade in Garching/Munich. The candidate will be fully involved in operating the gauges as well as interpreting the results from them. Long-time tests in Garching and an assessment of the applicability of this diagnostic to the ITER experiment will also be part of the research portfolio of the candidate.
Applicants should have completed their PhD in the field of experimental physics, preferably in experimental plasma physics. Strong experimental skills and a strong ability to interpret experimental data, as well as a strong academic record are expected. Good communication skills and the ability to do team work are expected.
The position is limited to a period of 2 years. An interesting and versatile research position is offered, the salary is according to the TVöD Bund grade E13.
The IPP seeks to increase the proportion of employed women in those areas where they are underrepresented and explicitly encourages women to apply for this position. The IPP is committed to employing more disabled individuals and especially encourages them to apply.
