Oxygen torus and its coincidence with EMIC wave in the deep inner magnetosphere: Van Allen Probe B and Arase observations [PDF]

Earth, Planets and Space, 2020
We investigate the longitudinal structure of the oxygen torus in the inner magnetosphere for a specific event found on 12 September 2017, using simultaneous observations from the Van Allen Probe B and Arase satellites. It is found that Probe B observed a

Inner Magnetospheric Oxygen Torus Induced by Electromagnetic Ion Cyclotron Waves

Geophysical Research Letters
Cold oxygen ions escaping from the ionosphere and temporarily trapped near the plasmapause form the oxygen torus. Mass‐loading by these oxygen ions significantly affects magnetospheric plasma processes.

Field Line Resonances and Cavity Modes at Earth and Jupiter

Frontiers in Astronomy and Space Sciences, 2022
Ultra-Low-Frequency (ULF) waves provide a means for the rapid propagation of energy and field-aligned current in planetary magnetospheres. At Earth, the ULF frequency range is usually defined as including waves with periods of 0.2–600 s; however, at ...

Io’s Optical Aurorae in Jupiter’s Shadow

The Planetary Science Journal, 2023
Decline and recovery timescales surrounding eclipse are indicative of the controlling physical processes in Io’s atmosphere. Recent studies have established that the majority of Io’s molecular atmosphere, SO _2 and SO, condenses during its passage ...

Does Ring Current Heating Generate the Observed O+ Shell?

Geophysical Research Letters, 2020
The Naval Research Laboratory (NRL) Sami3 is Also a Model of the Ionosphere (SAMI3) ionosphere/plasmasphere code is used to examine the effect of ring current heating during a storm. With a ring current heating function added to SAMI3, a cold thermal (

Advances in boronization on NSTX-Upgrade

Nuclear Materials and Energy, 2017
Boronization has been effective in reducing plasma impurities and enabling access to higher density, higher confinement plasmas in many magnetic fusion devices. The National Spherical Torus eXperiment, NSTX, has recently undergone a major upgrade to NSTX-

Effect of boronization on plasma-facing graphite surfaces and its correlation with the plasma behavior in NSTX-U

Nuclear Materials and Energy, 2018
Boronization is a Plasma Facing Component (PFC) conditioning technique widely used in tokamak machines. The National Spherical Torus Experiment-Upgrade (NSTX-U) applied this conditioning, using a plasma glow with a deuterated Trimethyl-boron (d-TMB) and ...
