  Self-consistent 3-D simulation of the HCX experiment magnetic section with electrons

These rendering of WARP simulation of an HCX experiment shows the beam propagating through the magnetic section, hitting a diagnostic plate and producing copious "primary" electrons which propagate upstream and generate "secondary" electrons when hitting walls.

  End-to-end simulation of the HCX experiment (QuickTime - 116 MB or 40 MB)

This WARP simulation shows the beam emitted from the source and then propagating through the three sections of the HCX: injector, matching section, and electrostatic-quadrupole transport lattice. The injector modeling employs a 3-D time-dependent description and uses an experimentally measured waveform for the beam extraction voltage. Once the beam reaches equilibrium, macroparticles are accumulated at the exit plane of the injector until sufficient statistics for high-fidelity simulation of the downstream system are attained. The accumulated set of macroparticles is then used to initiate a Z-dependent XY "slice" calculation of the matching section and the lattice. The slice mode of simulation assumes that the mid-pulse sections of the beam are well described by a steady flow of particles.

The movie contains three parts.

  Transverse simulation of merging beamlets showing coordinate-space view (QuickTime - 66 MB or 18 MB)

  Transverse simulation of merging beamlets showing XX' phase-space view (QuickTime - 4.5 MB)
