Particle buildup on single spheres in HGMS

Experimental and theoretical investigations of the initial and saturated buildup on single spheres are presented here. It is found that the time dependence of the initial accumulation radii can be expressed in terms of power laws and also that the saturation buildup can be well described by the static equilibrium model if the particle radius is used as a fitting parameter. Furthermore, a characteristic asymmetry of the buildup in the transverse configuration is reported and found to be of hydrodynamic origin.
