英文摘要It is well known that dust grains may affect the sheath structure when dust grains are dense. Typical fluid theory of a dusty plasma sheath assumes that the charging relaxation time of dust grains is much smaller than the time of dust grains across the sheath and the orbit motion limited theory is used to calculate the dust charge. Under these conditions, it is shown that dust charge in the sheath and the sheath parameters associated with dust charge fluctuate within a certain range. However, for fusion plasma, dust grains with large velocity and small radius can often be observed in the edge region of fusion devices. In this case, charge relaxation time may be much longer than the transit time moving from the sheath edge to the wall and then the dust charge can be considered constant. In this paper, one-dimensional multifluid model is developed to study a sheath of dusty plasma containing nanometer-sized dust grains with constant charge based on their long charging relaxation time and the short time across the sheath. It is found that the sheath parameters show monotonic variations and differ from the oscillation variations obtained from the sheath model which the charging relaxation time of dust grains is much smaller than the time across the sheath. In addition, the effects of dust grain density at the sheath edge, dust radius, and ion Mach number on sheath parameters are studied. Published by AIP Publishing.
