Major Features of VISUALIZER

VISUALIZER provides a means of viewing the output from a SPECT3D simulation. The images available for each detector are:

• Time-resolved images. The image seen at the detector for any of the timesteps in the simulation.
  • The image can be stepped through the times.
  • The raw image or any filtered image available can be viewed.
  • A spatial resolution can be applied to the image
• Time-gated images and spectra. If more than one time step is available, a series of time gates can be applied.
  • The starting time, width in time and the number of gates can be specified.
  • The gate can be either square or Gaussian.
  • The images can be stepped through the gate times.
  • The time gates can be applied to any of the unfiltered or filtered images.
  • A spatial resolution can be applied to the image
  • A time gated spectrum can also be displayed.
  • Time gated, horizontally, or vertically resolved spectra can be displayed.
• Time-resolved spectra. A plot of intensity against photon energy for one or more simulation times
  • A spectral resolution (E/ΔE) can be applied to the spectrum.
  • A table of the transitions that were included when computing the spectra can be shown.
  • The transitions can be displayed on the plot.
  • Individual transitions can be highlighted in the plot and identified in the table or selected in the table and highlighted in the plot.
  • The transitions can be filtered by element, ion stage, type (bound-bound, satellites and bound-free) and strength (oscillator strength or edge cross section).
  • Horizontally or vertically resolved spectra can be displayed, if available. The spectra can be shown for all pixels (2d contour plot) or as line plots for selected pixels.
• Zone dependent intensities.
  • The fractional contribution of each plasma zone to the intensity at the detector for any additional specified photon energy can be shown.
• Streaked spectrum. A plot showing the time evolution of the spectrum.
  • A streaked spectrum can be shown for two or more of the times in the simulation.
  • A spectral resolution (E/ΔE) can be applied to the spectrum.
  • A time resolution can be applied to the streaked spectrum.
• Drilldown. Plots show how quantities evolve along a chosen line of sight for a selected simulation time. Quantities include:
  • Temperature vs. depth
  • Electron density vs. depth
  • Mass density vs. depth
  • Intensity vs. depth for any extra photon energies
  • Optical depth vs. depth for any extra photon energies
  • Ionization fraction vs. depth for each DCA element and for non DCA elements if Propaceos file version 2.4 or greater is used.
  • Population for each atomic level in the atomic model file for DCA elements
  • Intensity vs. frequency
  • Optical depth vs. frequency
  • For DCA elements, the rate coefficients for a selected zone along the line of sight can be displayed.
• Band intensities Plots show how the appearance of a spectral band varies with time and position on the detector.
  • Spectral bands can be defined that cover a specified region of the spectrum.
  • The background to be used for each band can be specified.
  • Ratios of bands can be defined.
  • The integrated intensity of a band can be plotted against time or, for spatially resolved data, against position on the detector.
  • The width of a band, derived from a Gaussian fit, can also be plotted.
  • The ratios of intensities or widths of bands can be plotted.

The following displays are independent of the detector:

• Zone specific data
  • Data for zones that were specified in the simulation setup are shown in a table.
• XRD voltage. A plot showing the variation with time of all the XRD filters that were specified for the simulation.
