Despite its tremendous success, the Standard Model of particle physics (SM) leaves several important questions unanswered such as the nature of dark matter, the neutrino mass and its mechanism, and the matter-antimatter asymetry in the universe. Electroweak observables, such as those available in nuclear beta decay, form a wide landscape in which to perform stringent tests of the SM and look for signs of new, exotic interactions. Precision tests in beta decays, in particular, have been at the forefront of this effort and tremendous theoretical progress has been achieved in the last few years. Simultaneously, new experimental techniques and technologies are being introduced that sidestep many traditional systematic effects, such as Superconducting Tunnel Junctions (STJ) and Cyclotron Resonance Emission Spectroscopy. We will provide an overview of recent theoretical and experimental progress, and highlight the first use of STJs for precision beta recoil spectroscopy in the BeEST experiment. Finally, we will showcase their planned use at online radioactive ion beam facilities in SALER.
