Abstract

To take full advantage of advanced exotic beam facilities, target technology must also be advanced. Particularly important to the study of astrophysical reaction rates is the creation of localized and dense targets of hydrogen and helium. The Jet Experiments in Nuclear Structure and Astrophysics (JENSA) gas-jet target has been constructed for this purpose. JENSA was constructed at Oak Ridge National Laboratory (ORNL) where it was tested and characterized, and has now moved to the ReA3 reaccelerated beam hall at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University for use with radioactive beams.

In conclusion, advances in nuclear astrophysics are often driven by technical advances in studying the nuclear reaction rates. The construction of the JENSA gas-jet target represents such an advance and enables a new program of studies with exotic beams. First tests and experiments with JENSA at HRIBF have demonstrated its remarkable performance. JENSA has now been installed at ReA3 at the NSCL and commissioning is in progress. The first measurement with a radioactive beam will be a study of the 4 He( 34 Ar, p ) 37 K reaction of importance to X-ray burst nucleosynthesis [7] . This work was supported by U.S. DOE Office of Nuclear Physics and by the National Science Foundation (NSF) under Grant Nos. NSF PHY 08-22648 (JINA) and NSF PHY-1430152 (JINA CEE).
