The HILAT magnetic field experiment

Field-aligned "Birkeland" currents are associated with a variety of complicated plasma processes in the auroral ionosphere. The high sampling rate (20 vector samples per second) of the HILA T Magnetic Field Experiment, in combination with the other HILA T scientific instruments, will provide an opportunity to study the relationship of these currents with ionospheric scintillations, and their association with magnetospheric and interplanetary phenomena.
