VSim for Plasma Acceleration (VSimPA) is a flexible, multiplatform, high-performance, parallel software tool for computationally intensive plasma acceleration simulations. With its controlled dispersion algorithm, wakes and dephasing are accurately calculated. VSim for Plasma Acceleration includes reduced models for rapid prototyping of experimental designs, and its parallel capability can take advantage of the largest supercomputers to enable full-scale modeling. Work easily in the required dimensionality, whether 1D for the basics, 2D to capture transverse effects, or fully 3D to ensure all geometric effects are included.

VSim for Plasma Acceleration can be used to compute both laser-plasma and beam-plasma acceleration, including field-ionization induced injection. Use VSim for Plasma Acceleration for simulating controlled injection in a laser-plasma accelerator via colliding laser pulses. Model laser-plasma accelerations efficiently with a Lorentz boosted frame or the envelope model with VSimPA. Simulate actual experiments accurately by conducting large-scale simulations and model plasma acceleration with minimal numerical noise using VSim for Plasma Acceleration.

Vorpal, VSimPA's computational engine, has been used for multiple scientific discoveries, including the first "Dream Beam" discoveries, stable GeV acceleration, density-gradient injection, and the more recent "Trojan Horse" simulations. VSim/Vorpal has over 540 citations since it was introduced in 2004 in the Journal of Computational Physics. Its 45 citations per year make it the most frequently cited computational application capable of modeling plasma acceleration.

Tech-X understands that developing your own code or collaborating with an academic simulation research group are huge efforts that take time away from the research work itself and carry no guarantee of a well-supported and complete feature set. Designed for plasma-acceleration researchers in national laboratories or academia, VSim for Plasma Acceleration provides the necessary algorithms to handle accurate modeling of inherently complex plasma acceleration simulations with efficient parallel capability for very large-scale computations. Not only is VSimPA the only simulation code that is both fully-featured and commercially available, but VSim for Plasma Acceleration is supported by the same physicists, mathematicians, and engineers who developed the product. VSim for Plasma Acceleration comes complete with full simulation input file examples, so there is no need to invest valuable staff or student time developing or expanding a simulation code.

Regardless of your plasma acceleration modeling requirements, VSim for Plasma Acceleration is the economical simulation tool with a user-friendly front end and an easy learning curve that will decrease your time from concept to experiment design and interpretation. VSimPA easily installs and runs on Windows, Mac OS X, and Linux platforms.
