Dust growth in magnetised plasma sheaths

The evolution and character of plasma dust has wide-ranging implications for astrophysics and laboratory plasmas, including plasma processes and fusion devices. The local elec-tromagnetic elds can in uence the conditions for dust growth, leading in some cases to naturally occurring prolate-spheroidal dust shapes. In this paper we will present results for dust growth by ion accretion, under the combined in uence of an applied magnetic eld and the evolving electrostatic eld arising from the charged grain. Simulations of ion tra-jectories through a magnetised plasma sheath will demonstrate the inhomogeneity of mass loading on an isolated grain surface. The eect of grain shielding by orbiting particles, and the in uence of neighbouring charged grains, will ultimately be taken into account in our simulations.
