Highly Charged Ions (HCI) provide a unique probe that can be used to study the properties of radioactive nuclei. This is due to an interaction between the nucleus and the orbital electrons and has been used to uncover new nuclear decay modes, leading to observations of decay lifetimes different than the atomic lifetimes. Due to the unique challenge of producing and storing radioactive HCI, these types of experiments are quite rare. Here we report the commissioning of a new HPGe array for in-trap decay spectroscopy on radioactive HCI. The HPGe array is built around TITAN's Electron Beam Ion Trap (EBIT), which receives radioactive ion beams, charge breeds them, and stores them as HCI. Two future experiments are discussed: 1) the resonant stimulation of Nuclear Excitation via Electron Capture (NEEC) in 129Sb and 2) the observation of nuclear two-photon emission in 98Zr and 98Mo.
