Computational Physics

The Computational Physics group provides innovative solutions to complex problems using world class numerical and analytic tools. The group specializes in the analysis of applied physics problems in the areas of:

• basic plasma physics,
• inertial/magnetic fusion research,
• electrical gas discharges,
• high-energy-density physics,
• warm-dense matter,
• pulsed power systems,
• particle accelerators,
• electromagnetic pulse generation and propagation,
• micro-electronics shielding,
• microwave generation and transport,
• high power lasers,
• laser-matter interaction,
• radiation production and threat assessment.

The group utilizes Voss Scientific’s on site large-scale computing capability with three state-of-the-art parallel computer clusters, ranging from 32 to 128 processor cores. Tools available on these clusters include the L sp Suite, Mathematica, and other physics-related packages. As the original and current developers of the L sp code, Voss Scientific owns a full license (with source code) for the code and is a partner with ATK. The L sp Suite is a 3-D electromagnetic particle-in-cell code designed for large scale plasma simulations. The code calculates the interaction between charged particles (electrons and ions) and external and self-generated electric and magnetic fields. Some current applications are E-beam driven radiography, pulsed power accelerator design, heavy-ion fusion, KrF e-beam pumped laser, petawatt laser-plasma interaction, and plasma reactor.

We specialize in the development of custom software that includes scientific analysis, instrumentation interfaces, graphical user interfaces, database design, data visualization and simulation. We support both large and small scale efforts.

Voss Scientific's highly trained engineers have experience that ranges from embedded system design to EM simulation to fully distributed instrument control and data acquisition. Voss Scientific has offered this cutting-edge expertise to the scientific community since 1991 by providing a range of custom applications for Windows & Linux platforms.

Voss Scientific personnel have been major contributors to the development of high power microwave technologies for over 2 decades. Contributions include research and development of state-of-the-art high-power microwave sources and antennas, diagnosis of devices and their radiated environments, susceptibility effects testing, and electromagnetic hardening.

We have been key developers of narrowband HPM technologies with peak powers in the 100s - 1000s of MW; ultrawideband technologies with risetimes faster than 200 picoseconds and effective isotropic radiated powers (EIRPs) exceeding 10,000 MW; and patented GHz-bandwidth sensors used to diagnose the performance of this unique class of electromagnetic radiators.
