    In recent years the search for heavier and heavier elements has been undertaken predominantly through the exploitation of 48Ca-induced fusion-evaporation reactions on actinide targets. These superheavy elements have all been identified through correlated α-decay chains terminating in spontaneous fission. Due to advances in detection technology, data processing, and various data analysis tools for superheavy element studies it has been possible to perform the first multi-coincidence high-resolution spectroscopy experiments along these decay chains, namely studying moscovium decays with TASISpec.

    The desire for even Z-odd N experimental anchor points at the proposed magic proton number Z = 114 (Fl) to constrain and guide nuclear structure theory has led to an experiment being performed at GSI via the reaction 48Ca+242,244Pu, employing high-resolution α-photon coincidence spectroscopy, to study the decay chains of 287,289Fl.

    The upgraded version of the TASISpec decay station, including the eventual Lundium station, will be described, along with this the earliest experimental results will be presented.
