Charge state distributions of Ar- and Xe-ions in N2 and C in the energy range 0.2 to 1.4 MeV/amu

Description
During the first periods of operation a supersonic jet of N2 gas has proved to be a simple and reliable stripper in the UNILAC. Measurements of charge state distributions indicate some variations of the thickness over the active area of this target, but the influence on the average equilibrium charge state anti zeta is small. The values for anti zeta of Ar- and Xe-ions measured in the N2-jet or in C-foil targets are in accordance to previous estimations and measurements. (orig.)
Abstract (German)
Waehrend der ersten Versuche erwies sich ein Ueberschallstrahl aus N2-Gas als einfacher und zuverlaessiger Stripper in UNILAC. Messungen der Ladungsverteilungen zeigen einige Variationen in der Dicke im aktiven Bereich des Targets, aber der Einfluss auf den mittleren Gleichgewichtsladungszustand anti zeta ist klein. Die Werte fuer anti zeta fuer Ar- und Xe-Ionen, die im N2-Strahl oder und C-Folien als Targets gemessen wurden, sind im Einklang mit frueheren Abschaetzungen und Messungen. (orig./WL)
