Absolute nuclear charge radius measurements with EUV spectroscopy at TITAN EBIT
Year: 2025
Type: conference-paper
Abstract: Nuclear charge radii, a quantity crucial in many nuclear physics studies, can be extracted from H- and Li-like electronic transitions, even in heavy ions, when combined with atomic theory * **. The latter has progressed to permit such calculations from transitions in Na-like ions *** ****. Charge breeding to Na-like charge state eases experimental requirements. To this end, at TRIUMF's Ion Trap for Atomic and Nuclear science (TITAN) facility, we are developing a high-efficiency, flat-field grazing incidence extreme-ultraviolet (EUV) spectrometer, for the measurement of absolute nuclear charge radii of short-lived nuclides. It will be installed to the Electron Beam Ion Trap (EBIT), which is capable of electron beam energies up to 66 keV. The spectrometer is designed to optimize transmission efficiency in the EUV regime. The ray-tracing simulations done in Shadow3 ***** will be presented. The first measurement candidates are 211Fr and a suitable spin-0 isotope of Ra, which are relevant for atomic parity violation (APV) experiments and searches for time-reversal violating permanent electric dipole moments (EDM).
