(a) Schematic cross section and (b) photograph of the magnetized microdischarge ion source.
Computed magnetic field strength and radial component of the magnetic field, along the center of discharge channel. The position of corresponds to the exit of the channel. Negative positions correspond to the region upstream of the exit (inside the channel).
characteristics in voltage-limited operation.
Angular sweeps of the ion current density distribution in the beam, downstream of the discharge exit.
