vs. XOOPIC

Two-stream instability

  • Description: Formation of two-stream instability when counter-propagating electron beams have velocities much larger than their thermal velocity, in a background of cold ions.

  • Input file: original XOOPIC two_stream_ee_es.inp with modified grid size 256\(\times\)8 (from 256\(\times\)2)

Electron Beam Spreading

  • Description: Spreading of an electron beam when propagating along metallic walls.

  • Input file: original XOOPIC xybeam.inp with modified grid size 48\(\times\)24 (from 20\(\times\)20)

Deposition

  • Description: Ion deposition on a substrate surface, including a trench.

  • Input file: original XOOPIC deposition.inp with the following modifications:

    • grid size from 30\(\times\)100 to 32\(\times\)64 but keeping the same spatial resolution dx=dy=5e-8m
    • time step from 1e-13s to 0.5e-13s (better time resolution)
    • np2c from 1e4 to 1e3 (10\(\times\) simulated particles for better statistics)
