内容記述 | Collisional cross sections of particles are an important physical quantity. Collisions of ions with charged dust particles diminish low frequency waves such as dust acoustic waves and dust ion-acoustic waves. The collision cross-sectional area of charged dust grains depends on the velocity of an ion beam. The collision cross-sectional area of fine particles, i.e. glass beads, with beam ions is measured. It is compared with the geometrical cross section of the bead. The experiment is performed in a dusty double-plasma device with glass beads of 8.9 micrometers in average diameter. The ion beam current and energy are measured with a directional retarding potential analyzer. It is observed that, when the dust density inside the system is increased, the beam current ratio is reduced. From the reduction of the ion beam current, the cross-sectional area of the particles is estimated as a function of the beam energy. When the beam energy is increased, extinction becomes more dominant than scattering. | |||||
