• Total cycles: 30,000+ timesteps

Plasma Configuration

• Number of species: 2 (electrons + ions)
• Particles per cell: ~256
• Charge-to-mass ratio (QOM):
  • Electrons: -100 (normalized)
  • Ions: +1 (normalized)

Initial Conditions

• Background magnetic field: B₀z = 0.01
• Initial density: Uniform ρ₀ = 1/4 pi ρ

Numerical Methods

• Smoothing: Not applied
• Boundary conditions: Periodic in x and y
• Implicit solver: GMRES

Physical Units and Normalization

The simulations use normalized (PIC) units:
