Initial Distribution

25000 electron distribution

5000 electron macro-particle distribution

  • 5000 electron bunch text file - start @ z=0.1mm
    • 5000 electron macro particles (2pC bunch charge)
    • Gaussian transverse distribution (1mm RMS size (diameter), cutoff at 3mm)
    • Gaussian longitudinal distribution (50ps RMS bunch length, cutoff at 50ps)
    • Uniform Energy Distribution (0.130eV energy)
    • starting at z=0.1mm (Derived from distribution starting at 0mm passing through screen at 0.1mm)
    • space charge OFF
  • 5000 electron bunch text file - start @ z=0.1mm with space charge
    • 5000 electron macro particles (2pC bunch charge)
    • Gaussian transverse distribution (1mm RMS size (diameter), cutoff at 3mm)
    • Gaussian longitudinal distribution (50ps RMS bunch length, cutoff at 50ps)
    • Uniform Energy Distribution (0.130eV energy)
    • starting at z=0.1mm (Derived from distribution starting at 0mm passing through screen at 0.1mm)
    • space charge ON
  • 5000 electron bunch text file - start @ z=135mm
    • 5000 electron macro particles (2pC bunch charge)
    • Spatial/Temporal/Energy Distribution derived from simulations using above distributions starting at 0mm passing through screen at 135mm
    • starting at z=135mm
    • space charge OFF
  • 5000 electron bunch text file - start @ z=135mm with space charge
    • 5000 electron macro particles (2pC bunch charge)
    • Spatial/Temporal/Energy Distribution derived from simulations using above distributions starting at 0mm passing through screen at 135mm
