Abstract

The influence of intense ion beams on the density of a supersonic jet gas target along the ion beam path has been investigated for dissipated powers in the gas ranging from 7.8 mW/mm up to 4.0 W/mm. No effects have been observed in contrast to static gas targets where a significant reduction in gas densities arises already at dissipated powers above 10 mW/mm. Thus, for high beam currents such as in storage rings and/or for high gas densities a supersonic jet gas target is clearly superior to a static gas target.

    The impact of the increased background pressure is discussed in Section 5. Heat deposition from the 20Ne ion beam in the gas-jet was not included, since past studies have shown it will not affect the jet properties [11]. The other striking feature of Fig. 3 is the brief, sharp rise in volumetric density at the outer radial extent of the gas-jet.

    The JENSA target was initially constructed and characterized at Oak Ridge National Laboratory (ORNL), as described in this paper. The theory behind the gas jet target is well established, and thus the reader is referred to the literature for a fuller explanation (e.g. Ref. [1–16]). This paper will describe the specifics of the JENSA gas jet target construction and operation.

    Second, the small dimensions of a jet make gamma ray angular distribution measurements possible, given appropriately placed gamma ray detectors around the gas target. Third, previous studies [7] have shown that a supersonic jet is not affected appreciably by intense beam currents as opposed to extended gas targets where temperature changes resulting from the dissipated power in the gas affect the gas density along the beam's path [8]. This is particularly important, since the beam currents needed for measuring low cross-sections are in the range of tens of particle micro-amperes.
