Virginia Tech CAVE viewing thruster plume data. This is a 3D
thruster visualization of a BHT Hall Thruster plume. The CAVE
allows stereo images to be projected and interpreted by the
goggles to allow for an immersive 3D environment as seen by
the user. The view can be controlled by head movement, or by a
handheld wand. In this particular simulation, the shape of the
thrusters exhaust plume is being analyzed, along with the
potential, measured by color. The data was constructed via
Coliseum, the Virginia Tech CAPLab's plasma modeling program.

 | | This image is a plot of the potential
of the exhaust plume from a BHT Hall Thruster. A hall thruster
has a ring shaped particle source. This plot shows that the
particle stream will eventually converge in the middle from a
ring into a beam. You can also see that the surrounding area
has an elevated potential, showing that the beam has some
divergence. The data for this plot was generated via Coliseum,
the Virginia Tech CAPLab's plasma modeling program. The plot
was made in Tecplot. Credit to Alex Barrie. (May 2005) |
 | | This image is a plot of the axial
velocity of the exhaust plume from a BHT Hall Thruster. A hall
thruster has a ring shaped particle source. The streamlines
shown in this plot shows that the particle stream will
eventually converge in the middle into a beam. You can also
see that the outer edges of the plume diverge away from the
center instead of forming a tight beam. The data for this plot
was generated via Coliseum, the Virginia Tech CAPLab's plasma
modeling program. The plot was made in Tecplot. Credit to Alex

 | | This graphic is a plot of the beam
current density produced by an array of 3 (simulated) 30cm
NSTAR ion thrusters. The image was generated using the
parallel version of "Draco", which is central to Julien
Pierru's master's thesis. This version was designed to run
larger simulations such as SystemX. It has been developed as
part of the "Coliseum" project, which is led by a team
including members from the CapLAB at Virginia Tech, the Air
Force Research Lab, and MIT. (April 2005) |

current density produced by the (simulated) 40cm NEXT ion
thruster. The code ("Draco") which generated this image is
central to Lubos Brieda's masters thesis. It has been
developed as part of the "Coliseum", which is led by a team
