Abstract
We present systematic studies on the absolute density of hydrogen cluster b eams produced by using Laval-nozzles. Measurements of the cluster beam dens ity as function of the nozzle temperature and the gas input pressure result in maximum cluster beam densities for cases where the gas is already in a supersaturated state before passing the nozzle. The influence of the gas fl ow through the nozzle on the starting temperature of clustering and the tem perature dependence of the cluster beam density at constant gas flows are s tudied.
