Research output: Contribution to journalArticlepeer-review


We have investigated positively-charged fine particles in a cross-field sheath between magnetized double plasmas with different potentials separated vertically by the horizontal magnetic field. In the sheath the charges on the particles become positive, because ion current flowing from a lower high-potential plasma surpasses electron current coming across the magnetic field from an upper low-potential plasma. In this report, we have found a phenomenon that the particles can be sustained in the cross-sheath even when the levitation electrode is completely removed from the cross-sheath region. We also discuss the sheath structure between magnetized double plasmas.
