Meteor head echo radar data: Mass-velocity selection effects
TL;DR: In this paper, the authors show that while there does exist a bias in the measured head echo velocity distribution, it is smaller than those calculated using traditional specular trail data due to the different scattering mechanism, and also includes a bias against the low-mass, very high-velocity meteoroids.

Measurements of freely-expanding plasma from hypervelocity impacts
Nicolas Lee,Sigrid Close,David Lauben,Ivan Linscott,Ashish Goel,Theresa Johnson,J. Yee,Alex Fletcher,Ralf Srama,S. Bugiel,Anna Mocker,P. Colestock,S. Green +12 more
TL;DR: In this paper, an initial results from a study of electrical effects resulting from hypervelocity impacts at a Van de Graaff dust accelerator were presented. But, the results were limited to the impact-generated plasma and associated RF emission, and the rate of signal detection had a dependence both on material and on target bias.

TL;DR: In this article, the authors provide an overview of enhanced electron distributions in the radiation belts as well as approaches to VLF wave belt remediation including the use of either antennas or relativistic electrons beams in space to generate the very low frequency (VLF) waves.

Determining meteoroid bulk densities using a plasma scattering model with high-power large-aperture radar data
Sigrid Close,Ryan Volz,Rohan Loveland,Alex Macdonell,P. Colestock,Ivan Linscott,Meers Oppenheim +6 more
TL;DR: In this paper, an improved technique for calculating bulk densities of low-mass (3) was presented, with observations spanning almost three orders of magnitude from 0.01 to 8.g/cm 3.

Review of ICRF Experiments
TL;DR: The current status of ICRF experiments with emphasis on high-power heating results in tokamaks is reviewed in this paper, where the rationale for the use of the fast magnetosonic wave is described along with simplified models for the wave coupling and power absorption.
