Possibilities of photonuclear studies at the upgraded low-energy photon tagger NEPTUN — •Dmytro Symochko1, Thomas Aumann1,2, Martin Baumann1, Patrick van Beek1, Alexander Fuchs1, Yevhen Kozymka1, Daniel Körper2, Bastian Löher1, and Heiko Scheit1 — 1TU Darmstadt — 2GSI Helmholtzzentrum für Schwerionenforschung
The low-energy photon tagging facility NEPTUN at the superconducting Darmstadt linear accelerator (SDALINAC) has been constructed with the aim to study the photoabsorption cross section of the nuclei in low energy region under conditions of quasi-monochromatic gamma beam. Recently it went through the major upgrade which included a complete rework of the focal plane detectors. The setup now allows measurements in the 30 MeV energy bite in single spectrometer settings effectively covering energy range of Pygmy- and Giant Dipole Resonances. This provides us unique chance to study the photoresponse of the nuclei below and far above particle separation threshold (up to 35 MeV) within the same experiment under the same conditions. Upgraded NEPTUN was tested in the commissioning runs and aiming for the first production runs in 2019.
The talk will be focused on the results of NEPTUN commissioning and details of the planned experimental campaign, which will combine experiments at NEPTUN, HiGS and NewSubaru facilities.
