Experimental and numerical study of high intensity argon cluster beams

Features of formation of gas cluster ion beams

“…As expected with increasing P 0 the cluster peak shift to large cluster size and TOF curves acquired a larger width. The position of the cluster peak characterizes the mean size of ions, which is in good agreement with the calculated mean size of neutral clusters [16] shown in Fig. 6a.…”

“…Since the characteristics of condensate predicted by both models of condensation with two available approaches for nonequilibrium nucleation stage were found to be quite similar [16], the numerical results obtained only using classical nucleation theory will be illustrated below. The simulations were performed for the conical nozzle used in the experiments (see below).…”

“…[16], its main features will be briefly outlined here. The simulation of the flow of argon in the conical nozzle and in the free jet behind it was performed in the frames of parabolized NaviereStokes equations written in the natural coordinates formed by streamlines and lines normal to them [17].…”

“…Besides the nucleation stage the growing of the formed nuclei is also an important stage of the condensation process. For both tested models of nucleation stage the growth rate of droplet radius was assumed to be the same for all the droplets [16].…”

Influence of the Parameters of Cluster Ions on the Formation of Nanostructures on the KTP Surface

“…[12]. The cluster beam was formed by adiabatic expansion of high purity argon [13]. The cluster ion beam parameters were determined using the time-of-flight technique [14].…”
