The matrix assembly duster source (MACS) represents a bridge between conventional instruments for duster beam deposition (CBD) and the level of industrial production.The method is based on At+ ion sputtering of a pre-condensed Ar-M matrix (where M,is typically a metal such as Ag).Each Ar+ ion produces a collision cascade and thus the formation of metal dusters is in the matdx,which are than sputtered out.Here we present an experimental and computational investigation of the cluster emission process,specifically its dependence on the Ar+ ion angle of incidence and the cluster emission angle.We find the incidence angle strongly influences the emerging duster flux,which is assigned to the spatial location of the deposited primary ion energy relative to the cluster into the matrix.We also found an approximately constant angle between the incident ion beam and the peak in the emitted cluster distribution,with value between 99° and 109°.
