The most trusted tool for plasma acceleration research

fieldIonizeEx3D

VSimPA is a comprehensive software solution for scientists and engineers working on novel acceleration techniques. Users of VSimPA can run numerical experiments with ionization injection, colliding pulse injection, and down-ramp injection. By including reduced methods like the envelope approximation with or without phase tracking, VSimPA can model Laser-Wakefield Field Acceleration (LWFA) into depletion without fully resolving the laser wavelength, and controlled dispersion algorithms limit numerical artifacts.

VSimPA’s computational engine, VORPAL, 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. With thousands of literature citations since first described in 2004, VSimPA is the most frequently cited code capable of modeling plasma acceleration, and the most trusted tool for plasma acceleration research.
