Interaction between waves and particles
in space plasmas
One of the fundamental goals of space physics is the study of energy
transfer in plasmas. This energy can be present in the constituent
particles of the plasma, various waves that may exist in the plasma, and
in the configuration of the magnetic field in the plasma. There are many
ways, not all of which are understood, for the particles of the plasma
to acquire energy in such a way that the plasma is unstable to certain
waves, which obtain their energy from the unstable particle distribution.
These waves, in turn, dissipate and give their energy to the particles. This
back-and-forth energy transfer plays a key role in the dynamics of several
regions, including the bow shock and the auroral zone.
Current Projects
Cluster 2
We have built and are calibrating four instruments called CODIF (COmposition
and DIstribution Function). Each instrument, which is part of the
CIS (Cluster Ion Spectrometry) package, will fly on one of the four satellites
which will comprise the Cluster 2 mission. Launch is scheduled for
summer 2000.
Fast Auroral SnapshoT explorer (FAST)
Our group works with the TEAMS (Time-of-flight Energy Angle Mass Spectrometer)
instrument on FAST.
This instrument measures 3-D distributions of protons, alpha particles,
helium ions, and oxygen ions as well as mass spectra of minor ions in the
plasma.
My research is focusing on ion conics: ions which are accelerated
transversely to the geomagnetic field and then convert some of their energy
to motion along the field as they move into regions where the magnetic
field is weaker. This work has been published in
Geophysical Research Letters
and elsewhere.
Recent Past Projects
Advanced Composition Explorer (ACE)
Our group has built the Solar Energetic Particle Ionic Charge Analyzer
(SEPICA) instrument on ACE.
In the photo below, I am holding the high-resolution collimator and electrostatic
analyzer for SEPICA in the deflection and imaging test configuration.
The engineering model high voltage supply, which is designed to supply
a nominal 30 kV to the center deflection plate of the electrostatic analyzer,
is mounted above the fan. (Photograph by Rick Miller, February 1996).
