Event Title

P-44 The Effect of Tail Stretching on the Ionospheric Accessibility of Electron Beam Experiments

Start Date

Description

An electron beam fired from a satellite in orbit could carry energy flux into the ionosphere if the beam is fired into the loss cone. Such an experiment would allow for the accurate mapping of magnetic field lines. High energy electrons are preferred for stability, but the loss cone becomes dependent on field line curvature for relativistic particles. We looked at how tail stretching of the magnetic field affects the accessibility of 1 MeV electrons to the ionosphere. We found that accessibility is increased off of the midplane, but the high curvature region near the midplane of the magnetotail shows significantly reduced accessibility.
