Current Research Projects:

CROSSED-FIELD DEVICES

Computational modeling of crossed-field devices, including diodes, magnetrons, and crossed-field amplifiers. We are interested in issues of stability and noise in these devices. This classical problem dates back to A. W. Hull in the 20's.

Letter--Rapid Current Transitions in a Crossed-Field Diode

ECR MODEL

We have started a preliminary model for an ECR plasma source using the OOPIC code. The electromagnetic heating mechanism of the ECR is investigated. A whitepaper is now available which describes the model:

Preliminary ECR Simulation Using XOOPIC

HIGH PRESSURE DISCHARGE MODELING

Computational modeling of AC plasma display panel cells. This research involves modeling high pressure gas discharges in a number of gases, including Ne, Xe, and He at pressures of up to 1 atm, with electric fields up to 1E7 V/m.

XOOPIC
Object Oriented Particle in Cell Code (OOPIC). This code includes models for the following:

Cartesian Geometry
Cylindrical z-r Geometry
Orthogonal Non-uniform Mesh
Electrostatic Fields
Electromagnetic Fields
Static Magnetic Fields
Boltzmann (inertialess) electrons
Relativistic Particles
Multiple Ion and electron species
Monte-Carlo Collision Package

Boundary Conditions:

Conductors
Dielectrics
Emitters (Field and Beam)
Incoming and Outgoing Waves (EM)
Symmetry Boundaries

The boundaries are very flexible - complicated shapes can be added from the input file (without recompiling). Boundaries are presently required to consist of line segments between grid nodes.

The walk through for this code was put together by Peter Mardahl.
