Elin Eriksson, PhD student at IRF and Uppsala University, studied the acceleration of electrons in space around the world, explaining why she had chosen to focus on this topic:
"If we understand what is happening in space around the world, we can try to understand the areas to which we can not send a satellite," she says.
The study of the dynamisation of electrons in near-Earth space: kinetic scale studies using multi-satellite data contain measurement analyzes of the four European Cluster satellites captured 18 years ago, as well as measurements of measurements of the four US Magnetospheric MultiScale satellites, MMS, implemented since 2015.
Ionized gas material
Almost all visible matter in the universe consists of ionized gas, also called plasma. Plasma is usually made up of positive ions and negative electrons. When the charged particles are accelerated, radiation is emitted. Radiation from, for example, supernova explosion residues are created by accelerated electrons. Most of the cosmic object observations we have are in the form of this radiation.
– I have studied the acceleration of electrons in space around the world. Thanks to faster measurements of MMS satellites, I was able to identify how electrons are accelerated in smaller areas. It has been found that electrons are accelerated in the same way in many space regions around the world despite their different plasma environments, "said Elin Eriksson.
The Institute of Space Physics, IRF, provides instruments for the MMS and cluster.
The Institute of Space Physics (EFW) cluster in Uppsala is responsible for the EFW instrument (electric fields and waves) that performs field and wave measurements. The instrument, present on each satellite, examines, among other things, how the outer shield of space against space, the magnetic field, interacts with the solar wind.

About the cluster (ESA)
Magnetospeheric MultiScale – MMS Magnetospheric MultiScale, MMS, is a NASA mission consisting of four identical instrumented satellites, filmed from the Kennedy Space Center in March 2015. These satellites use the Earth's magnetosphere as a laboratory to study the microphysics of three basic plasma processes : magnetic return, acceleration of energy particles and turbulence.
