“…• bending angle, which had been installed previously as a postseparator behind the "Separator for Heavy-Ion reaction Products" SHIP [43,44]; sometimes, this device was referred to as the "HElium Charge-exchange Kaleidoscope" (HECK) [45]. The reused parts included mainly the three magents and two of the power supplies as well as the vacuum chamber housing the focal plane detector.…”

Superheavy elements / Transactinides / Physical preseparation / Recoil separatorSummary. In recent years, significant progress in the field of superheavy element research has been achieved thanks to a novel combination of techniques from different fields. This "physical preseparation" approach includes the coupling of an ancillary setup -typically a chemistry apparatus or a counting setup -to a physical recoil separator. This latter preseparator removes unwanted nuclear reaction products as well as the intense heavy-ion beam associated with superheavy element experiments and thus isolates the evaporation residues of the nuclear fusion reactions. These are guided to the separators's focal plane, where they are extracted and available for further transport to external setups, e.g., by a gas-jet. In this overview, the development of physical preseparation is described, and experimental results from nuclear chemistry and physics that were achieved with "preseparated" isotopes are summarized, with an emphasis on results relevant for superheavy element research. The covered topics range from chemical studies in the liquid as well as in the gas phase, the measurement of nuclear decay properties and of atomic masses. Preseparation was already shown to be a very powerful approach in these studies and promises to allow further progress in superheavy element research.

Recent progress in experiments on the heaviest nuclides at SHIP

et al. 2022

Understanding the atomic and nuclear properties of very heavy and superheavy nuclides is one of the main objectives in experiments at the recoil separator SHIP at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany. This article summarizes recent experiments performed on isotopes of the elements with Z = 102–105. The radionuclides of interest were produced in heavy-ion fusion-evaporation reactions with lead and bismuth targets and separated from the primary beam by the velocity filter SHIP. The studies by $$\alpha $$ α –$$\gamma $$ γ spectroscopy experiments, direct mass measurements and laser spectroscopy employed the SHIP decay-spectroscopy setup, the new COMPASS detector, the mass spectrometer SHIPTRAP, and the laser spectroscopy setup RADRIS. This article briefly introduces the experimental approaches and discusses selected results providing a more comprehensive picture of the nuclear structure around the deformed neutron shell closure at $$N=152$$ N = 152 . Future perspectives to extend such experiments towards other regions in the heaviest nuclei will also be addressed.
