The new gas target system at the shallow underground laboratory Felsenkeller Dresden — •Anup Yadav, Konrad Schmidt, and Daniel Bemmerer — Helmholtz-Zentrum Dresden-Rossendorf

In experimental nuclear astrophysics, reaction studies with low cross sections are of interest. To measure those reactions directly, feasible possibilities include underground facilities to shield against cosmic rays and hence reduce the detector background, high intensity ion beams, and highly pure and stable targets. All those features will be available at the currently constructed und tested gas target setup for the shallow underground laboratory Felsenkeller Dresden. This setup combines a highly localized gas wall jet and an extended, static, windowless gas target. A unique feature in nuclear astrophysics applications is the in-situ monitoring of the jet thickness by a laser interferometry system. The talk will report on the gas target setup, its first thickness measurements, and suitable science cases in nuclear astrophysics.
