Abstract
A gas-jet target for cluster fragmentation experiments has been studie d in the inlet pressure range of 0.1-5.5 Torr corresponding to a targe t thickness range of 10(13)-1.2 X 10(15) at. cm(-2). The total now has been found to be in quantitative agreement with the Poiseuille formul a in the pressure range of 1.0-5.5 Torr. The profile of the jet is in good agreement with the (cos theta)(5/2) law expected in the viscous f low regime in the inlet pressure (P-0) range of 0.1-5.5 Torr. From cro ss section measurements using the inlet pressure range of 1.5-5.5 Torr , the target thickness has been found to be proportional to P-0(2) as expected. The target thickness characterization has been extended in t he range 10(13) to 10(14) at. cm(-2) from measurements with cluster be ams.
