Animated Visualizations

Animated visualizations are a vital tool for anyone who wants to understand and communicate the behavior of complex systems. The Tech-X team has the experience and expertise to help you create animated visualizations that will engage and inform your audience. The following examples below were made from our physics simulation software results.

Magnetron

A Magnetron simulation created using VSim.

Multipactor Comparison

The video shows a side-by-side comparison of the 2 secondary electron models and how the resonance zone of the realistic model is much wider than that of the simple model.

Arrayed Waveguide Grating Simulated in Demultiplexing Mode

In this simulation, the fundamental mode is launched using a unidirectional wave launcher. Matching Absorbing Layers prevent reflections from simulation boundary. B_z is displayed in this visualization. The wave is coupled to the ring and next to the second waveguide.

Silicon Waveguide in Silica Cladding

Shown in the visualization are positive and negative contours (red and blue) of B_y. The clipped views with multiple contours of B_y are shown in the multicolored scenes. The unidirectionality of the mode launcher enables arbitrary placement of the wave source along the waveguide. Matched Absorbing Layers (MAL) reduce reflections at simulation boundaries.

Microring Resonator Simulation Setup and Visualization

The simulation geometry is set up in VSim using the graphical user interface. The visualization displays B_z. Matching Absorbing Layers prevent reflections from the simulation. The wave is coupled to the ring and next to the second waveguide. The fundamental mode is launched using a unidirectional wave launcher.

Colliding Laser Pulses Launch an Electron Beam into a Plasma Accelerator

This simulation visualization by Estelle Cormier-Michel of Tech-X was one of the 2011 U.S. Department of Energy’s Scientific Discovery through Advanced Computing (SciDAC) program OASCR (for Office of Advanced Scientific Computing Research) award winners.

Laser-Wakefield Accelerators "Dream Beam"

All different incarnations of laser-wakefield accelerators. It shows the background electron density (surface) plus some high-energy particles (beam) as particles.

Magnetic Field

The electron density in a 2D simulation of the expansion of a two-component plasma (electrons, ions, at same temperature) in an ambient magnetic field (out of plane). It initially expands symmetrically, but due to the charge separation (on average faster electrons than ions), the electrons get pulled back into the center, leading to some radial oscillations. The ambient magnetic field causes the rotation. That’s a configuration as encountered e.g. after ignition of the target in an Inertial confinement Fusion experiment. This shows that the debris created in an ICF chamber could be confined by a strong magnetic field, thus protecting e.g. the optical inlets into the chamber.

Photocathode Modeling

Modeling ICRF Heating in Alcator C-Mod

Geometry Construction

This movie gives some detail on the construction of the geometry used to simulate Alcator C-Mod’s field-aligned ICRF antenna in VSim. CAD files from the antenna (provided by MIT engineers) are imported to the VSim grid; thereafter, the antenna module is embedded in a half-torus rendering of C-Mod’s vacuum vessel. Finally, an equilibrium plasma density profile (provided by MIT scientists) is loaded into the vessel.

Electric Field Contours

Vertical component of the electric field induced by the field-aligned ICRF antenna in the Alcator C-Mod device, in a simulation which imports plasma density and magnetic field profiles from experimental data. The geometry of the simulation is described in Modeling ICRF Heating in Alcator C-Mod: Geometry Construction. The phasing of the antenna straps is [0, π, 0, π]; complex patterns of fast wave propagation into and through the plasma core are clearly visible.

Plasma with Electric Field

Vertical component of the electric field induced by the field-aligned ICRF antenna in the Alcator C-Mod device, in a simulation which imports plasma density and magnetic field profiles from experimental data. In this animation the plasma profile is also shown; the data is the same as was used in Modeling ICRF Heating in Alcator C-Mod: Electric Field Contours, though the view is slightly different. The phasing of the antenna straps is [0, π, 0, π]; complex patterns of fast wave propagation into and through the plasma core are clearly visible.

Midplane Electric Field

Vertical component of the electric field induced by the field-aligned ICRF antenna in the Alcator C-Mod device, in a simulation which imports plasma density and magnetic field profiles from experimental data. In this animation the toroidal midplane of the device is shown; the data is the same as was used in Modeling ICRF Heating in Alcator C-Mod: Plasma with Electric Field, though the view is slightly different. The phasing of the antenna straps is [0, π, 0, π].

Poloidal Plane Electric Field

Vertical component of the electric field induced by the field-aligned ICRF antenna in the Alcator C-Mod device, in a simulation which imports plasma density and magnetic field profiles from experimental data. In this animation a two-dimensional poloidal cut across the antenna coax feeds is shown; the phasing of the antenna straps is [0, π, 0, π].
