[Denmark] PhD Scholarship on Relativistic Electrons in Electric Discharges at Technical University of Denmark

PhD scholarship on RELATIVISTIC ELECTRONS IN ELECTRIC DISCHARGES
is available at DTU Space, Copenhagen, with start date September 1st 2010, or as soon as possible thereafter.

Abstract
The position, which is funded by The Danish Council for Independent Research | Natural Sciences, is related to a mission planned for the International Space Station: `The Atmosphere-Space Interactions Monitor` (ASIM) for observations of extreme thunderstorms and their influence on the atmosphere. The project will study how electrons are accelerated to relativistic energies in electric discharges in the atmosphere. The question has been raised after the surprising observations from satellite of high-energy radiation from the atmosphere above powerful thunderstorms, and from lightning and laboratory discharges. The radiation is bremsstrahlung from electrons that are accelerated to unexpected high energies. The acceleration process is not well understood but is interesting because it influences the dynamics of the discharges and their effect on the atmosphere.



DTU Space has developed numerical methods to study the phenomenon with very high precision of the electron dynamics. These will be used to explore the conditions for electrons to reach high energies and their influence on the discharge dynamics. The simulations will be evaluated relative to measurements from laboratory experiments. The study will be conducted in collaboration with researchers at the Technical University of Eindhoven, Holland, and the Russian Federal Nuclear Center – VNIIEF, Sarov, Russia.

QUALIFICATIONS:
Candidates should have received a master`s degree in science or engineering, or a similar degree at an equivalent academic level, at the time of employment. A candidate is sought with good background in physics and numerical methods, and with a reasonable mastering of the English language.

APPLICATION:
We must have your online application by 28 June 2010. Go to: www.dtu.dk/English/About_DTU/vacancies.aspx and select the position advertisement. Then open the link `apply for this job online` and fill in the application form and attach all material that should be given consideration in the assessment.

APPROVAL and ENROLMENT:
The study will be under the DTU Space PhD network `Space Science and Technology` www.space-phd.dk/English.aspx . The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the requirements for enrolment and the general planning of the scholarship studies, go to www.dtu.dk/English/education/Phd_Education/PhD_guide.aspx.

SALARY and APPOINTMENT TERMS:
The salary and appointment terms are consistent with the current rules for PhD degree students. The study will be based on the DTU Space `South` office, Juliane Maries Vej 30, close to downtown Copenhagen. The student will organizationally be under the Department of Solar System Physics.
