Ph.D student in Space Physics (dnr: 2.2.1 - 164/26)
The Swedish Institute of Space Physics (IRF) are searching for a highly motivated person to the research programme Solar System Physics and Space Technology (SSPT) in Kiruna to study ions with low energies around comet 67P/Churyumov-Gerasimenko.
Description
Ions with low energies in the upper parts of the atmospheres of planets and moons are hard to detect directly with particle sensors. At same time they play a very important role. The Rosetta mission to comet 67P/Churyumov-Gerasimenko gave us the opportunity to directly measure low-energy ions. The spacecraft was negatively charged most of the time, attracting positively charged ions and enabling detection down to the lowest energies.
Job description
The goal of this project is to understand how ions born in the upper atmosphere the comet, decouple from the surrounding neutral particles and are energized to escape velocities. Ions with low energies are highly affected by the environment around the spacecraft itself, and we have to compensate for that. In this project we combine analysis of observations made by the Rosetta spacecraft close to comet 67P/Churyumov-Gerasimenko with simulations of ion trajectories around an electrically charged spacecraft. The simulations are made using SPIS (Spacecraft Plasma Interaction Software).
Qualifications
To be admitted for studies at third-cycle level you are required to have completed a second-cycle level degree or completed course requirements of at least 240 ECTS credits, of which 60 are at second-cycle level (Master’s level), or have an equivalent education from abroad, or equivalent qualifications. In addition to these requirements, 120 ECTS need to be within the physics subject area. The requirements do not need to be fulfilled at the time of application but only at the enrolment.
- Good knowledge of the programming language Python
- Experience of spacecraft data analysis
- Experience of modelling using SPIS (or similar software)
What we offer
We offer a workplace with flexible working hours, up to seven weeks of vacation per year, comprehensive healthcare including wellness programs and health benefits.
Equality, equal opportunity, and diversity are fundamental principles in our workplace. We work in an equality-integrated manner, meaning that gender and diversity aspects are considered in daily work and all decision-making processes.
Terms
The position, placed in Kiruna, is for four years. The start date can be as per agreement. Salaries are negotiated individually.
Applications should include a CV with a publication list, a personal cover letter outlining relevant experience, and the contact information of two professional references.
